That's what I would expect. In which case, it would just go back to the mod team being irresponsible with how they perform and communicate banning someone.They do know.
They have this, too.
Though I will have to be fair: mods don't have any obligation to inform third parties about a ban. But they do to the person they're banning. This is all under the assumption that yoghurt really doesn't know why he was banned and no one on the mod team is willing to tell him.
I don't personally need to know the details, but this isn't the first time on this forum that I've seen mod actions being done without informing the person who did the offense why it was done. Maybe these were just random incidents out of countless mod actions. Maybe this is business as usual. Either way, it doesn't feel right.
