A topic was created by mikeywith around a year ago about Bitmain.Farm :
https://bitcointalk.org/index.php?topic=5209185.0I discovered it yesterday.
It really is a fake site. But the question here are that does Coinpayments.net knows about it? We can not expect that a company will have always their investigation team correct about everything. Maybe reporting them properly will help them to delist it. I believe they have an account in the forum but not sure which handle they use. If anyone knows the user then PM them.
