There's different expectations for IRC vs most other social/chat platforms because of the structure and history. IRC has traditionally been run as a non-commercial community project so admins and server ops haven't had the same incentives for commercial palatability and IRC being older and a bit more obtuse to get into meant it didn't get the same attention in the cases where it's users do get into trouble. On top of that given it's a protocol instead of a single company there's a bit of separation where each server doesn't put pressure on all the others.
