I have the WAVES wallet address, the name of the scammer registered through GoDaddy (may be fake), their ETH wallet address. Not sure how to go about getting a subpoena from GoDaddy to obtain more information about them. Who's with me?!
Seems like that they have either deleted or renamed every thread that they've had on this forum with random titles.
Anyways, their site is down and I couldn't find any archived version of it anywhere on archive.is so that's just too bad. I think that the chances of you catching these scammers is extremely small. The legal trouble isn't worth the 1 eth honestly.
There is one post that quoted their bounty OP: https://bitcointalksearch.org/topic/m.28082098: http://archive.is/nrv3G).
OP and everyone, take this as a lesson. ICOs are risky to invest in. Exit scams are frequent in this field.
