The point is, you're trying to protect the current Bitcointalk's traffic right?
In capitalism, competition is inevitable, if sooner or later altcoinstalks can gain a good traffic, the campaign in this forum should increase their payrate to make it better. Isn't this is good? the new campaign is only compete against the other campaigns, but they will need to compete against other campaigns and altcoinstalks in order to get a good poster.
