I really don't know but I don't think just any shitposter could pretend to be me and get away with it for more than 2 or 3 posts, tops. And although I did run a bounty campaign for a token called SHITCOIN once, if my account suddenly started advertising a new coin or ICO or something, it would probably raise some eyebrows. So in that way its probably not worth very much.

Here's an interesting question: what would you do about old accounts that likely changed hands where the former owner was a scammer but the new owner is just a shitposter?
