The two additional incidents linked in there (in post 1 and 3), were both actioned by a moderator, the user spoken to, and the behaviour hasn't been repeated. The one in your third link was aimed at me directly, not a hexbear user, and occurred before hexbear federated with us.

So, 4 events in total, 2 of which involved hexbear users, and 2 of which occurred before hexbear federated with us. All 4 of which received a moderator response and communication with the user, which stopped the behaviour in question.

Notably, 3 of the users accused of being chasers are trans, gender diverse or gender questioning themselves. And I'm not going to kick a trans person to the kerb for behaviour that can be addressed by talking to them.
