I'm now clear with this thread that if Justice needs to be done, either it should be done in full or nothing.

That either DTs tag Yahoo if they are intended towards tagging the users who advertised Yobit in their signatures or none should be tagged. But what about those who were either banned by Yahoo or left the campaign themselves either before or after that X10 advertisement arrived? As they were also a part of Yobit's campaign some time before, should they also be tagged for advertising Yobit or they are set free? If so, how will they be found now?
