This actually should be the best approach to every problem or cases of cheating in the forum. But the irony of the matter is some of the accounts hunting for alt accounts are actually alts who might want to rank-up in a more smart way. Again, if they report to moderators, moderators will surely dismiss the report as bad because the evidences presented are not clear enough. When they decide to tag such accounts, the feedback won't have effects because they are not on DT.

I believe this is the reason they create topics upon topics for similar cases trying to drag the attention of DT members to do the tagging. I saw one the other day who has not made any other post than commanding DT members around to do the investigation and tagging for them.
