It turns out cryptohunter has been going at this for a very long time:

Please retreat back to the altcoin spam boards, you'll be much happier when nobody reads your posts

Of course, and eventually someone has had enough of the trolling, and tags him. And the more he digaran complained about it, the more red trust he collected.
Digaran's English was less good than cryptohunter's, but his troll level was more advanced than just making crap up about users.

I think he gave up after his -16, although some say he may be using an alt-account now.
