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.

      No target. I will keep this open as long as it’s possible. It’s up to others to start as many Lemmy instances as possible, and the Lemmy devs to create a better join-lemmy with a rotating ‘recommended server’ preferring smaller instances. But that’s difficult. Because you also don’t want 1000 users to land on someone’s Raspberry Pi instance without backup which they can just stop if they get bored of it. Same issue goes for Mastodon as well… but that’s being worked on.

        Tangential question but it’s been on my mind. Should mods be encouraging images to be posted on outside image hosting services (Imgur or something) to reduce the load on Lemmy.world? I actually don’t know how much images affect the server.

          Nah… It’s only 27GB of images right now. I have around 800GB space, and can have disks (cheap HDDs in case of images) added to the server. Also pictrs will support S3 in the newer version. But good that you’re all thinking with me!

    OK that makes sense, I was trying to sign up and couldn’t figure out why everything was timing out. Sorry if my attempts looked like spam.

    edit: it still doesn’t work for me btw

    Last time a website I was managing was bombarded with spam signups, I set up a regular expression to check for the incredibly distinctive format the spammers were using… then it reports success but doesn’t actually create the account or send an email. Spam problem over.

    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

    Lucky me, I guess, since I use a masked email address that looks fake too (anon addy). I really dislike to give my email address when testing Reddit alternatives.

    Sounds frustrating. Thanks for doing what you do and letting us join your server! Hope the captcha works out.

    User on kbin here, just tried to sign up to lemmy.world… looks like everything crashed and burned when tried to sign up there.
