I believe in passion for a cause and maybe this one is good enuff so personmark to all. A good reason for exchanging personmarks? Most are given just because someone frequents a board no matter if dd is offered or good stock referrals or whatever should be criteria.
I have given a few just so I see folks that I know when I visit other boards.
Therefore, the system is flawed just for the reasons above which have nothing to do with cheating..
