Jumper his moonlight sig campaign does not end yet but he jump to join on big paying camp.
On the other hand what can you say about them joining on sig camp and busting their competitors and gain fame to have slot on every camp they wish to join?
The Pharmacist is not earning from 2-signature campaigns simultaneously.
They are not breaking any forum guidelines, rules or signature campaign criteria.
What is your point?
There has not been a single instance, as far as I know, of any current DT member tagging someone that applied for the same slot in a signature campaign as them and that person even remotely being considered competition for that slot. Do you have any evidence that these people are "busting their competitors and gain fame to have slot"?
They do not have a monopoly on signature campaigns, or the participants; they literally would not even be relevant to signature campaigns if the signature campaign managers themselves did not grant merit to these ratings. This tells you that the campaign managers probably agree with these ratings, for the most part, and if this is the case you would not be getting into the campaign regardless of their rating; it is just saving campaign managers a few seconds per spammer.
Anyone that puts forth any effort whatsoever into their posts or time around the forum is unaffected by these ratings, unless you consider the positive affect of scaring away spammers or forcing them to improve.
I don't see the problem.
