And what about signature campaigns not allowing to post in certain forum section why do you think there is difference between them and sig camp which are forcing people to post in certain sections?
What you posted above is different because it's not a forced bump (I myself don't do this because I have nothing to say in the threads).
The difference between signature campaigns forcing posts in sections vs. them discounting posts in others is that the former is more limited than the latter. The former pushes one to post in Gambling for example (FJ, always resort to it) to which one may not be able to find enough discussion that they can be constructive in during the week.
I frequent Scam Accusations, Reputation, Meta and Gambling. If I'm forced to post in Gambling then I'm sucked out of 3/4 of my discussions. When I'm limited to boards that are not Scam Accusations, Reputation and Meta, then I can still cover ground in other boards, sifting through the shitmounds of spam to find some good things.
And I think the percentage is closer to 98%
