A profile sniper is someone who often has a weak argument, and on the losing side of an online argument, who resorts to viewing the profile of the user they're arguing with to find things to make fun of them for in an attempt to gain leverage in an argument by irritating the other user.
"So, you have to snipe my profile to find something to use for a counterpoint. Go get some valid points to back your argument instead of being a neckbeard profile sniper."
Equivalent to calling BS, but when you're playing Flappy Bird and you deem your loss unfair because it didn't seem like the bird went anywhere near the pipe, rather into the pipe's invisible hit box. So it's as if someone unfairly shot your bird down with a sniper rifle.

Quora is a forum where you can ask and answer questions about a wide variety of topics.
A Quora Sniper is a Quora-centric troll that:
Posts flamebait or loaded questions.
Lays in wait for answers to the above they can savage (or ad hom people).
Refuses to provide their own answers to questions posted.
This sort of behavior detracts from the value of Quora.
Person 1: I answered a question about The Balkan Wars and someone from Serbia is calling me a racist and a Serbophobe!
Person 2: Be careful answering some questions on here; it looks like you found a Quora Sniper.
