Once upon a time, Leafy was actually a good youtuber.
He posted funny stories of things that happened IRL, which could have been fake or real, but were funny nonetheless. I actually enjoyed the stories and watched simply because some of the retardation that supposedly happened to him IRL was funny as fuck.
Then he began reviewing youtubers.
That is when shit went downhill. He did not attempt to make original content anymore and simply shit talked people with an increasingly pompous and nasally voice. He made himself look like a Paragon of Virtue and Justice when it came to the quality of other people's youtube video's while his own video's perpetuated the cycle of shit that is the bad side of YouTube.
Finally, when he is no longer relevant, he begins drama fests with people like Keemstar (who would have died out eventually when people stopped caring) and they fed off each other like mutual parasites. Both would have just faded off into obscurity but by feeding off each other in increasingly disgusting displays of negative video's against both each other and other people they managed to keep themselves in the lime light.
They included others similar to them like Pyrotechnical or whatever the fuck his name is nowadays. They continued this on and on until people just got tired of it and they started the "apology" phase in order to still keep themselves relevant while retaining the pity subscriptions they got from the whole debacle.
Now Leafy realizes he has strayed from his original path but all his subscribers are used to and only want his subpar and garbage content as well as crass attitude instead of his original content creation that his channel centered around when it first started. Hence he now falls back to the drama of being "hacked" in order to get attention as its the only way to keep his channel afloat and relevant nowadays.
The more attention you give the longer he survives is the TL;DR of the story. Just like every other YouTuber that follows the same template as Leafy nowadays.
