This question (which is currently closed as off-topic, and deleted) comes from a known troll account. They're currently suspended on two other sites for trolling, and their MSO account was nuked entirely for repeated trolling.
Believing that this is also a troll question, I flagged this post as Rude/Abusive. However, a moderator declined it, citing lack of evidence.
Why was that? Was I correct in flagging this?
