It's all a matter of perspective.
If you're a normal (overrated) person, with IRL obligations, with work, with family and a social life, you even within yourself find it pointless to troll, bully or show off on the internet. We've all seen it around.
Dwelling on it, expressing frustrations through any medium, to anyone left to listen, etc... all those end up consuming this hypothetical "you".
Imho, best way to go about it is simply ignore it, one of the advantages of the internet being this capability (of irl phasing someone out) and keep doing your thing!
