i don't think creating multi cards is violating the rule, unless you are confirmed to be laundering. ( they change the rule without prior notice is expected but ridiculous)
they reserve rights to ban anyone at no time, explicitly. no exceptions including me. i will take notice if more open accusation is appeared against this site that proves the scam.

if your account is verified, then you are less likely get banned though, anyway, if above is the case, then i will spread this thread to his announcement.

Ps i used those virtual cards too.
