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.
Anything can happen but can you quote the link where theymos said this statement. Do you even know what a Signature campaign or bounty is ?
The Bounties can never end because many ICO and Services are paying to get their products get more visibility.
Have you ever thought of Ads in a TV channel. If one TV channel stop taking ad, will the companies stop advertising ? NO.
They will move on to the 2nd best Bitcoin Forum and start their advertisements.
