Be honest, what do you think tagging people for ICO bumping is going to achieve? Their goal is to cause ICO threads to be on the first few pages of the ICO sub. These accounts are not used (to my knowledge) to trade. If anything, tagging these accounts gives legitimacy to someone trying to sell these kinds of services to someone using these services from a particular person.

I am strongly against any ICO bumping service, but this is something that needs to be dealt with by the administration.
