If you believe that anyone who does any of these things is actually trolling you...I would advise leaving the internet until you actually know what you're calling people, unless you're alright with looking like a moron. But because if I don't put a disclaimer I'll keep on getting comments: every one can be put into trolling but at an ultimate level not every person doing any of these things is trolling. Now we don't need any more comments like that. 8D
Telling the Rules: Oh God you wouldn't believe how many people on here, if you give them just one link to the FAQ or simply tell them that some of their work in their gallery is against the rules, the immediate response is, "TROLL TROLL TROLL TROLL GET AWAY TROLL I DON'T CARE I CAN DO WHAT I WANT STOP TROLLING ME ALREADY!"
Criticizing: Recently I came across yet another artist who started crying when someone gave him the slightest bit of criticism, mostly revolving around anatomy of women he draws (which, honestly, was just a bit too exaggerated). He put his comments off and left, I'm serious, a note to 'The trolls'. :I
Giving an Opinion: Okay, this one's a little tricky because some people do use it for the purpose of trolling; for instance they say that they'll hate something/someone, knowing that fans of this something/someone will get pissed, and when confronted will jump directly in front of the 'IT'S MY OPINION FREEDOM OF SPEECH SHIELD'. But then again, the people who do this are more than obvious and it should be obvious to spot out those who are truly just letting out their opinion and don't mean any harm.
Disagreeing...that's a no brainer. For many if someone disagrees with them, they believe that it means the other is trying to piss of them off. And not thinking like you...pretty much the same thing.
With all that though...no. :I
I've said it before a million times and I'll say it a million more: stop trying to slap every bit of internet lingo you know on every person around you. Stop acting like everyone's out to get you and piss you off. They're not. Really.
