So some spam signups just happened (all username12345678@gmail.com 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.

    I ran into the issue on my instance as well, but checking the Captcha option in admin settings, stopped the signups for me.

        I did it in the database, so if you can access your database I can assist.

          My instance also experienced this. I’m the only active user (I made it a day ago), but the user count is up to 2K now. It stopped after I enabled captchas, but I want to remove these spam accounts so they don’t cause issues elsewhere.

          I don’t even have a slight clue as to what I should look for in my database.

            If you haven’t figured it out yet or got a response yet, hop onto the instance admin group on matrix for Lemmy (details are on the GitHub or join Lemmy page somewhere I believe) and one of the many other folks running instances can probably walk you through it
