Is the IRC channel dead?
I've posted there previously (under username "phildo") sporadically over the past few years (the last time being a few months ago...). I tried to log on just now, and it said it required use of SASL? So I created a new account (phildo3) and signed on, but when I tried to post it said "#hashcat You cannot send messages to this channel whilst the +m (moderated) mode is set.".

Has the IRC channel been archived or something? Moved somewhere else? Killed altogether?

Or am I just being dense and don't know how to use IRC properly XD
It's moved from Freenode to Libera:
HashMob created a bridge with a channel on their discord today - so if anything - it's extra busy.
