Locking threads for “Harassment, slander, threats” seems like a bad way of going about it.
The slander is still there, anyone can read it, but what changes is that now nobody can reply to correct it. I think that just makes it worse.
The author should probably either get a warning with the thread remaining, or if it’s serious just deleting the thread outright.
For those who haven’t seen it, I’m talking about how this thread was handled (and for the record, while I can’t speak about the allegations of what happened outside the forums, on RMW the sentiment towards VS was generally rather negative, and I’ve never seem anyone punished for sharing those opinions).
