Apologies for the poor video quality on this one but it seemed daft to waste time on a video explaining why I don't wast time on trolls.
This video taught me that we each have individual definitions of what constitutes a troll.
In my opinion: If you're young and immature, you're not a troll. You're just a kid. If you're an adult and just type "gay", you're not a troll. You're just a prat. If you're trolling a troll, you're not a troll. You're just wasting your time and the real troll is ahead on points. No malice, no troll.
When you know your personality sucks, that you will be disliked no matter WHAT you do, it almost makes sense to give the world a reason to dislike you. If you project a persona that YOU would hate too, being hated becomes almost a means of control. Don't let them control you, even for a second. Don't hate them. Pity them. They are sick and they can never change. Just block them and forget they exist (apart from the "pet" trolls that genuinely amuse you ofc).
