Dumb question, what is trolling

I have seen things about trolling on this community what does trolling mean?

Deliberate offensive or provocative posts (or actions) that occur consistently against certain people.

Specifically in IF

Buzzing an active tower, flying inverted in airliners in crowded areas, rude callsigns, etc…

What is buzzing an active tower?

Flying very close at breakneck speeds…

Ah okay, so basically the casual server.

Trolling is acting inappropriately, often ruining someone else’s experience, for a laugh. It generally reflects poorly on the person trolling.
