I understand that some people with signature campaigns do not provide anything to a discussion and they just write silly unintelligent idiotic things that doesn't improve the discussion at all.
There is a very effective solution for signature spammers, report them to their campaign managers or to mods with help of "Report to moderator" button. The first choice is certainly better, because each decent campaign manager will remove such a user, and maybe even add them to black list.
Stop the hate against people who have signature campaigns.
At this forum, as well as in real life there is a lot of hate, but also love. I wouldn't say it's hate in most cases, it's mostly envy that stems from the fact that not everyone can be in top paid campaigns. Most of those who are invested effort and time have the privilege of participating in signature campaigns, and if anyone hates us for it, so be it, hate is very bad for health...
