Today, a bunch of new instances appeared in the top of the user count list. It appears that these instances are all being bombarded by bot sign-ups.

For now, it seems that the bots are especially targeting instances that have:

Open sign-ups

No captcha

No e-mail verification

I have put together a spreadsheet of some of the most suspicious cases here.

If this is affecting you, I would highly recommend considering one of the following options:

Close sign-ups entirely

Only allow sign-ups with applications

Enable e-mail verification + captcha for sign-ups

Additionally, I would recommend pre-emptively banning as many bot accounts as possible, before they start posting spam!

Please comment below if you have any questions or anything useful to add.

Thanks, I am an instance admin and I realized I did not previously have captcha on. That’s been rectified now.

Not that I get a ton of signups anyway. Ever since the join-Lemmy page of instances was reworked, I’m not popular enough to be listed :(
