While what you describe sounds dubious, I am not sure it qualifies as Blackmail; I think a necessary part of Blackmail is threatening to reveal something, or in some way damage another person if the money or services desired are not forthcoming; I think what you described is some form of Extortion, a broader set of crimes, which are related to Blackmail, but are normally based on coercsion, rather than a threat to reveal information.
I would do some legal research and pin down the exact crime commited, and see what evidence you can legally gather. If you are serious about this, I would not do too much more without consulting an attorney, as you can destroy your case based on how the evidence is obtained.
If you don't risk anything of yourself by going to jail or anything, yeah sure do it.
If you do risk going to jail, just let it go.
But don't take my word for it, I'm a troll who doesn't help people.
I think they said you were some kind of acne thing, lol- they called Hisoka a troll. Your extended reaction is too funny, lol; you really have to just ignore all of that stuff.
