agree with you totally!i see groups like this everyday and yet people who goes there are not there to discuss they method, they come there to discover new ones and that is why it doesn't work. (just my opinion)
no sane marketer will ever discover his winning campaigns and strategy; not even when is part of a skype-group or any group (unless he gets something significant in return)
*disclose
I agree. Anyone that knows how to get $0.01 US clicks is keeping their mouth shut.
