IRC? That thing's still alive?
There's still at least one group that only even exists on IRC (no website, no presence on aggregators like mangadex, but still indexes their releases on mangaupdates). Of course, the leader is a reclusive loon....
God, I remember when the last
big scanlation group whose scans were only available via IRC bots died. #null, I just checked mangaupdates and their last scanlation was apparently released in 2011. They had a website but the website was used for copy-pasting IRC commands. Good times. I'm old.
