I don't think my post is hard to understand, I said "they will move to other campaigns", which mean they will have incentive to post and they can post whatever they want including discuss about mixers.
It's an exception for users who only want to promote "non gambling project" but it's only 5%-10% of them, after all there's always an user willing to promote anything, so the traffic will not go down.
Are you implying that for every banned mixer campaign some "other" campaign magically popped up? Because that didn't happen.
Some managed to get a spot in a different, non-mixer campaign, but if the total number of available spots is much lower, and if pay rates are in decline, there's less overall incentive and the activity goes down.
Just because there still are some campaigns operating, doesn't mean banning mixer campaigns had no impact on activity as you previously stated.
