Erm, I feel a bit sorry for Relic on this as people seem to hating on them when they are testing a brand new system, you know what is worse than not banning a cheater? Banning a non-cheater, false positive are the bane of any new system and had they started banning there was a chance that the system could could end up banning the wrong people which would lead to even more outrage...
this is why listing there names could be a very bad thing. also the idea was that relic would give them a second chance so that ruins that possibility as well.
