@kemona_halftau @benjae it also has an IRC client which is configured to connect to libera (formerly freenode) by default and somehow is so easy to misconfigure to log in with SASL when you don't actually have an account that for years it was a cause of annoyance that random thunderbird users who had the same username as you would try to log into your account and cause SaslServ to spam you with failed login messages
(I don't remember if they finally fixed that or if libera disabling failed login notifications by default just made people stop complaining)
