Here you can see 2 day old post warning about the danger of not using email/captcha verification:
https://lemmy.ml/post/1345031
And here are stats of lemmy platform where it shows that we gained 200 000 lemmy users in 2 days:
https://lemmy.fediverse.observer/dailystats
Another tracking site with the same explosion in users: https://the-federation.info/platform/73
What do you think? Is it some sort of a bug or do people run bot farms?
Edit: If you want to track if there's any sudden bump in amount of users on our instance you can do so here: https://the-federation.info/node/details/50294
Edit2: It's been now 3 days and we went from 150 000 user accounts 3 days ago to 700 000 user accounts today making it 550 000+ bot accounts and counting. Almost 80% accounts on lemmy are now bots and it may end up being an very serious issue for lemmy platform once they become active.
One of the admins announced in the comments that they will be defederating bot instances, you can track defederated by us instances here: https://fba.ryona.agency/?reverse=lemmy.fmhy.ml
Edit3: It's now 4th day of the attack and the amount of accounts on lemmy has almost reached 1 200 000. Almost 90% of total userbase are now bots and so far our instance didn't experience any sudden increase in the amount of created accounts.
Edit 3.1: my numbers are outdated, there are currently 1 700 000 accounts which makes it even worse: https://fedidb.org/software/lemmy
There's definitely bot farming. Someone i know on Mastodon posted this yesterdar: Post in spanish
this is a translations made by google and I changed some words: "I set up an instance of Lemmy, to test a few things. I passed it on WhatsApp to a group of people, so they could look at it. I always had the federation turned off because it's a test instance and I don't want to screw anyone in other instances. I had the configuration that it sends me an email if someone asks to register. Eventually trying configurations, I ended up leaving it with open registers. Last night I got about twenty new account registrations, with names that seem to want to imitate subreddits (ragequit, yolo, hype, things like that; I don't know subreddits like that but it sounds like they might exist). And various things:
All of this seems to me like a nightmare to moderate. And the truth is that I do not blame the instances of Lemmy at all that are blocking the instances that have open registration."
@Kaizen@lemmy.fmhy.ml @zinklog@lemmy.fmhy.ml Do we have email verification on our instance?
Edit: sorry for ping but situation may be a bit urgent :x
Edit2: I'm not even sure if I pinged them xD
on lemmy.world they activated captchas which, apparently, is an option.
We have them too but captchas only help so much, using both captchas and email verification makes it harder to do these things than when having only one of those security measurements.
and neither will prevent from spambots coming from other instances
Yes, but limiting the issue is a good practice. And if some instances become basically bot instances we can defederate from them when bots start being active.
Of course. All in all these are things that usually happen when a platform gets traction and publicity. Hopefully better tools to deal with this will come soon.
We already got lots of activity on github so we should have better tools in not far future. For example I saw few minutes ago a pull request on github with sorting options for 1 hour, 6 hours and 12 hours which already makes this platform better than reddit.
Wait that's so cool now I'm hyped
I also made an issue on github asking for top 3 months, top 6 months, and top 9 months sorting options and someone started working on it within an hour. Now the code is waiting for the merge https://github.com/LemmyNet/lemmy/pull/3226.
Those captchas don't work properly rn appearently andthe Devs wanna remove them for next update and rewrite them later on from what I've heard
Just a heads up, I think it's in the GitHub issues as well
There's an issue to bring them back
AFAIK no, it hasn't been setup yet
