I read comment by the admin that if the merit system fails to reduce spam from the website, he might take decisions like removing the signature campaigns. This is scary for me. I am not eligible for any campaign yet but I was hopeful to get enrolled in one. If this is going to be implemented for sure, I might not be comfortable participating in discussions. I will though read posts by other members for information needed.
I do not think that'll ever happen, FYI signature campaign guys don't get paid for posting crap! They're under stricter rules and their posts are always under scrutiny. The campaign managers I have been under are very strict and another fun fact for you, look at Chip Maker campaigners merit collection, and the stats posted by Dark Star. Signature Campaigns have always kept this forum clean, and those who fail to do so are removed.
