I am not getting any benefit even in bounty hunting.
You mean spamming. You get no more benefits from spamming Bitcointalk (thousands of posts), Twitter (must be tens of thousands of posts) and Facebook (same numbers). Delete your posts, they won't be missed. Even better if you cancel your internet subscription.
Over a thousand post op literally is a spammer.. and the tag on his profile says he's a bounty cheater. Op is just too many things in one.
Op, if you no longer have use of your account, (as it's obviously useless), you can go to your profile and edit your login details to some random one. Your password, just put in any random combination and then save. This way when you try login in, it you won't as you no longer know the password.(don't cheat again) when you create a new account ( because you will and already have multiple) make sure not to repeat same mistake again.
