There are really only two possibilities for the reasoning behind this post that I can see. Neither of which are exactly in your favor.
1.) You have wayyyyy too much time on your hands. It would also appear that you have a grandiose sense of self-worth and have convinced yourself that you are some kind of master manipulator by lying to self-proclaimed liars on the internet. But you should absolutely pat yourself on the back with that "I cause 70% of the drama on this website, it's so easy!" comment as it just screams confidence. It becomes a little redundant past a certain point, don't you think? Whatever helps you pass the time, I guess.
2.) This post is a simple bait to get users who are known to have a little bit more of a "colorful imagination" to doubt themselves and become paranoid. Beat that dead horse until the bones break! Truly sociopathic material, really.
Unfortunately, I don't think either one of these options shed any sort of positive light on the person behind the screen as both reasons are completely and utterly pointless xD
It's just too easy...
