[Solved] Temporarily closed signups because of spam signups (self.lemmyworld)

So some spam signups just happened (all [email protected] format e-mail) This caused bounced mail to increase, causing Mailgun to block our domain to prevent it getting blacklisted.

So:

  • Mail temporarily doesn't work
  • I closed signups for now
  • I will ban the spam accounts
  • I will check how to prevent (maybe approval required again?)

Stay tuned.

Edit: so apparently there is a captcha option which I now enabled. Let's see if this prevents spam. Registrations open again.

Edit2 : Hmm Mailgun isn't that fast in unblocking the domain. Closing signups again because validation mails aren't sent

Edit 3: I convinced Mailgun to lift the block. Signups open again.

Becareful with this. There’s a clear trend of massive amount of bot accounts flooding lemmy as a whole

I am not sure there's anything in that that denotes "massive amount of bot accounts". Seems more like "a lot more people made lemmy accounts than stuck around" which is unsurprising.

Why would a bot account show up in one of your graphs and not the other?

they're waiting to use the bots when the community is large, over a long period of time. This way it'd be hard to detect the bots.

I take my comment back, you are totally right. There are a few ghost town instances with 80k users. Super obvious if you look at the active users vs users, or users vs comments. My bad -_-
