you seem to be on a hunting spree for cheaters and rule breakers. try to differentiate between what is actually wrong and what is not.
^--- This.
Much like the guys who just "spam" their Twitter retweet and Facebook post links in all of the Altcoin campaign threads... if the thread is specifically setup for users to post their referral links (and they're allowed/encouraged to post multiple times) then there is "no harm, no foul".
I think both should be ban from forum. They are not only connected just came out here for share referral link.
If he was spamming his referral link across multiple, unrelated threads in other boards, then sure... get out the "BanHammer"™... but in this instance, it is unwarranted.
