This is call for all moderators of Mastodon instances with open registration policy: let's cooperate, let's fight botnets together. We can share mail domains and blocked IP addresses.

I am trying to keep registrations open for the next big wave of Mastodon migration, which I believe is inevitable.

There are very few actual humans, willing to do some sustained harm - most of the malicious activity are bots. And we can track where they register and operate from. Ultimately, we can learn who is doing this shit and who pays for it...

Let's say that there is a payment for a subscription that fails, due to insufficient funds. I hate portals that make it impossible to just simply try again, even though you refill the account. But if you just add the same card again, it works.

Looking at you, @kagihq, but you are far from being the only ones...

A few years ago I designed a way to detect bit-flips in Firefox crash reports and last year we deployed an actual memory tester that runs on user machines after the browser crashes. Today I was looking at the data that comes out of these tests and now I'm 100% positive that the heuristic is sound and a lot of the crashes we see are from users with bad memory or similarly flaky hardware. Here's a few numbers to give you an idea of how large the problem is. 🧵 1/5
ok, so even though it's not connected to their gateway, an ordinary (correction) ZBT-1 seems to work just fine :)
