"Gaslighting" has a different meaning (go watch the movie; it's a classic).
I haven't heard the other two terms, and wouldn't be able to guess what they mean.
Sea lions spend all day fighting over [arbitrary thing] to impress potential mates. I'm certain this happens on social media, and that most potential mates are as impressed as they are by an actual sea lion. :-)
Gaslighting seems to have mutated to mean "asserting strongly that something isn't true, which I've personally experienced to be true", or in the more extreme cases, "...which I believe to be true."
IMO it's an annoying corruption of what was actually a rather useful term, but there you go.

Concern trolling seems to be too specific a term.
