well you try to only allow one account per user. but we all know that the way you track this is through our IP, so you get another computer at another location and post from there.
It is very simple.
note if you post baseless pumps, that this will hit a dime next week, or a dollar next year, or this will never go down. Those remain, and those that try and warn of a scam get punished. So what the board is left with is a whole bunch of newbies reading all these pie in the sky posts. Their emotions get the best of them and boom they are sucked in and in 2 days down 50%.
IHUB is a forum for those to get their emotions played with, which in the end costs them money!
