I have no problem as I said having an alt account but when joining contests, spreading manipulated lies just because you do not like someone with an alt account is abusing the opportunity of the freedom of speech. It's personal hate and cheating.
Didn't you also use altaccount when you tried to start a new casino review business that didn't work out, and it was later discovered this was you? 
I am not blaming or protecting anyone but there is no rules that altaccounts can't be used in forum competitions, or for starting a new business.
Even talking bad about other members they don't like is not forbidden, but nobody respects that chicken behavior.
