He tries to raise a 100 BTC fund based on the "success" of his previous, much smaller funds over the last year. This is the prototypical way for a ponzi to be set up: lots of small deals to boost confidence / build rapport of investors to vouch for you, and than go in for the big fish (i.e.: this offering). He locked the thread after refusing to reasonably (i.e. actually answer instead of deflect/argue) answer any of the questions posed by myself, along with OgNasty and a newbie forum poster.
Second:

User tried to set up/partner with a HYIP over a year ago. For those of you that are not aware, HYIP is just another term for ponzi scheme.
Third:

User tried to start a cryptocurrency that was meant for pump and dumping.
Edit:
He unlocked the thread under point 1 so he could post with this sockpuppet: https://bitcointalksearch.org/user/golku-910307
