turddrop 

You know, where you post something divisive, rude, or offensive to a forum or chatroom to stir everyone up and then log off immediately for the night.

- What did you think of Eric’s post last night? Everyone was flipping out.

- It was a total turddrop

Turddropper 

A person who creates a post and then disappears never to reply to comments reactions.

That turddropper left an interesting post and then disappeared.
