I've actually PM'ed EcuaMobi asking him to please provide me with the results of his own analysis, and it was inconclusive:
Update: I haven't found final proof against betcoin.ag so I don't think promoting it deserves negative trust. There are some suspicious things so personally I wouldn't promote it but the benefit of the doubt could apply. However I do think it would be more responsible for anyone to research a site before promoting it. This is valid for everyone and even more so for staff and trusted members.
Indeed I found it to be inconclusive. However I did find suspicious things and I strongly advice you or any other not to promote it. That would be more responsible in my opinion.
I just didn't find enough evidence to
demand it or to add negative trust to those who promote it.
Regarding special attention to Staff, DT or trusted members I think we all should be more careful about who we promote, however I think this is specially true for Staff members because newbies see that Staff label on their profile and may think the prompted site is endorsed by the forum.
That's not the case with DT members, there's no 'DT' label which may confuse new members. Very trusted members should be extra careful too.
