It's your personal opinion, that it is a gambling website...
It's his personal opinion, which happens to coincide with the personal opinion of makebtc's hosting provider. Random d00ds shutting down websites are all part of the fun that is Ponzi. Man up, dust yourself off, and stop bawwing.
I'm not even sure that nrd525 is taking credit for something they actually did. Any proof of your actions, nrd525?
I would have hoped that Mr MakeBTC would have used a host which didn't mind whether the sites do gambling or not. After all, gambling is legal in plenty of places. It's possible that some busybody complained to the host and threatened to sue them for some part of (for example) a fraud which claimed to be an investment when actually it was gambling, then the host took it down out of an abundance of caution.
So, I'm guessing Mr MakeBTC has a back-up somewhere but it'll take him a few days to get it all sorted out. The site has been through worse; got hacked a couple of times already and he repaired it.
Still, it would be nice to hear from Mr MakeBTC on what is probably still the only dedicated, open, thread on his website anywhere on the internets...
