You have to understand that there is too much con-artists borrowing the identity of respectable persons to conduct scams. It's fine if you don't wish to provide your ID, but having a forum/exchange mod confirm it would be necessary.
Look at the "Moderator Votes" section at
https://btct.co/security/BTC-GROWTHThe only barrier to entry in becoming a moderator is capital. The moderators have not been chosen because they are any more trustworthy than any other individuals. It's a bought position, and this should be kept in mind whenever someone attempts to use moderator status to lend legitimacy to any 'proof' they raise. Namworld's investigation to find that the BTCGrowth website is hosted on the same IP and utilizes the same service providers is more proof of identity than the word of an exchange moderator. Now, if it was the exchange administrator , burnside, who had instead verified his identity, then I'd have accepted this, or some confirmation posting on the long-standing blog for the man instead of a newly created website.
