I've been just logging in recently doing Advent stuff and occasionally zapping one of my pets for giggles, never commenting on anything, visiting profiles/forums, or anything, and suddenly...
Who? Wut?"You have been blocked by Mental. Please refrain from further contact with this user. Doing so could result in a warning for Harassment!"
When did they change it to notify you who has blocked you? No idea who this person is or why the random block when I've done jack-all on the website in years, but it kind of seems like bad form to actually actively notify someone that a person has blocked you instead of a quieter method, where you only discover if you try to interact with them. It opens the doors for the revenge-seekers or whatever. Are quiet-block systems unusual now?
