There seems to be an ongoing spam attack against some networks, trying to make postmarketOS and other related projects (Mobian, Arch Linux for PinePhone, ...) look bad. They're impersonating various pmOS team members as well as some linux-amlogic community members and other folks.
They're known to target irc.pine64.org and inevitably other networks. This seems to be targetted spam by "supernets"/"HOUDINI" spammers.
Ugh...
