What would be a good word for someone (other than Troll) that only ever posts negative , antagonistic or snide comments on forums?

Troll is both overused and often wrongly used and words like antagonistic , misanthrope or bigot feel too broad in definition?

I've seen Gaslighting used a few times for Trolls and Flamers but i can't imagine that would be a globally understood term...
