Can we get image upload back?

it’s been 4 months-- any update on this?

Personally I say just leave hosting of images to dedicated sites for that purpose. Your efforts are better left to dealing with how to render them. That being said, I use to be in charge of managing abuse on a site that has an average of 20 million posts a month (seriously).

The way I essentially defeated these kinds of attacks was with an image scanning service. It scans for anything NSFW and blocks it. Sometimes things would make it through but once an admin flagged it we could use that to block the users IP and account. It’s not cheap but the volume is also not huge yet for lemm.ee so it might not be too bad.

Please please do not implement an invite system.

The success of a forum like this depends on people being able to join and express their thoughts freely. Reddit and digg would never have gotten where they are if they had a closed system.

I almost didn’t join lemmy because the first two instances I heard about (lemmy.ml and beehaw) had closed registration. I think I applied and then forgot about it for 2 weeks. Thankfully I saw a post about lemmy on reddit yet again and finally found an open instance.

Don’t let the actions of a few scumbags ruin a good thing for everyone. You’ll be giving them exactly what they want.

For step 6 - are you aware of the tooling the admin at dbzero has built to automate the scanning of images in Lemmy instances? It looks pretty promising.

so how do I upload an avatar?

I think the images should never be cached from other instances in the first place, that is a huge oversight in pictrs since not only does it have the potential to cache unwanted content but also causes the images hosted to rapidly accumulate which isn’t ideal as it increases storage requirements which is unfair to people who want to self-host a personal instance. Hosting a personal instance should not have monstrous storage requirements or serious liability risk due to caching all images automatically, it should only cache what is uploaded to the Instance like profiles and banners, and posts that include images from the Instance.

I have reservations about allowing fully-invite based registrations on lemmy instances. While I do think it might be good to have invites as a way for users to skip filling out an application I don’t really like the idea of requiring them like Tildes does, makes it feel like an elitist exclusive club of sorts having to beg for an invite from users. I don’t think it should be an alternative to application-based registration, but rather a supplement to it, if someone can get an invite from users that’s great but if not they should still be able to write an application to join, this could be extensive and also lower priority since you could get invites but should still be an option available.

Account requirements really depends on what they are and what they restrict (also who on the instance is allowed to impose restrictions). For example on instances with downvotes enabled I think score/upvote requirements are a bad idea since it essentially means that people who disagree are locked out, like on Reddit with karma restrictions, I do not support this, it creates an echo-chamber where unpopular opinions. It’ll also lead to upvote farming if there are negatives due to having a lower score.

Comment or post requirements would just lead to post or comment farming similar to vote farming, though it’s not as bad as score-requirements since people making posts and comments naturally (whether they are liked or not) can’t be taken away by other people based on opinions (only if they break the rules and get posts removed, which isn’t even remotely similar since they broke the rules).

Limiting image uploading is a fair requirement in my opinion since uploads can be particularly harmful if the uploads are malicious, and also uploads aren’t really needed since people can externally host almost all their images without the need for uploads.

When it comes to DMs and restrictions around them I feel like that should be up to individual users to decide to allow private communication from certain users or not, or even to allow DMs at all, this shouldn’t be something globally applied to people, maybe it could be a default in User settings and have a requirement set by the Admins but people should be able to turn it off if they don’t care or want to accept messages from new users, I know I certainly will, I hate being nannied when it comes to who’s allowed to send me messages, IMO Annoying or uncomfortable DMs are a fact of life and I prefer to deal with issues when they happen rather than block anyone who’s a new user that might want to talk to me, it’s one of the things I hated that Reddit does without giving me the option to opt out and receive messages from everyone.

I think having a Machine-Learning based system to identify Malicious images is actually a pretty good idea going forward, I know how some people feel about AI and Machine-Learning but I think it’s probably our best defense considering that none of us want to see it, it might have False positives but I’d rather than than to allow CSAM to live here. Ultimately the choice is have ML scanning or Disable pictrs here, I think ML is the better option because people are going to want to have Avatars and without pictrs that isn’t possible (unless Lemmy adds support to the UI for externally hosted Avatars and Banners).

I’m going to be a part of an invite only community?! Of course, given the circumstances, this is pretty fucked. But I feel kinda fancy right now.

Thanks for all you do on lemm.ee

You need to update the site to reflect these changes - I was trying to upload a banner and got the incorrect error “image too large”

Going from completely open to invite-based is what I’d call overcompensation (you’re overestimating how willing people will be to invite)

It is now impossible to add an avatar or banner to profiles because the only way to do so through the UI is uploading to the instance. There’s no way to add an external URL. Just wanted to point that out in case it wasn’t intentional. Very understandable if that’s something we have to sacrifice for the time being.

Edit: I noticed that images will upload to the account’s home instance instead of the community’s home instance. This means that one workaround for the time being to change your lemm.ee community’s icon and banner is to create an account on another instance and then add that account as a moderator to your lemm.ee community. You can then use that external account to change the icon and banner of your lemm.ee community because images will be uploaded to whatever instance your account is on instead of lemm.ee.

Forums have existed on the internet forever and and have already dealt with this thousands of times previously. You don’t need to overthink it or reinvent the wheel. It didn’t stop forums existing very comfortably in the past and isn’t an issue that should be that different to deal with today.

Simply limit image uploads to a certain account age threshold and karma threshold and you will eliminate 99% of the ability to abuse this.

So, Lemmy.World images seem to be ‘re-federating’ here. I couldn’t find any news items over there, but… did the CSAM issue finally get patched at the Lemmy software level?

I understand that admins need to take whatever measures needed to protect themselves from legal pursuits

At the same time I hate to see the promised federated network revert to what commercial platforms have become, karma and account age requirement, phone and identity verification , forced 2fa and what not.

Maybe lemmy should implement a shared database whereas if an admin of an instance marks a post as potentially illegal, it gets replicated to other instances automatically and gets in queu for deletion.
