@matrix Is there a way for admins to easily detect if they have a spammer? Like log messages, they can look at, or better yet, alerts they can set up?

@adam @matrix I export metrics using Prometheus and from there can create alerts based on high new user count

@y0x3y @matrix But the problem is people sending [unsolicited] messages, not people registering for accounts.

Wouldn't a better metric be the number of different users messaged by a single account in a short period of time?

Detection routines should be detecting the bad behavior that we actually care about. Otherwise the problem will just morph into slowly signing up for accounts and then sending tons of messages later.
