As a result, the quality of posts, merits, ranks, etc. will be pushed into the background.
The number of posts will be the priority: the more posts - the higher the conversion \ more attracted users - more profit for the advertised site. This scheme will only be able to stimulate more posts, and this will inevitably lead to a decrease in quality.

Also, it should be noted that the more posts, the higher the chances of getting more merits - simple math. It all comes down to the fact that spammers (for example, spamming news posts) will be in a priority position. Why write a longread when you can write together a bunch of short posts (150-200 characters that meet signature campaign conditions)? The answer is obvious. 

The world is changing and the rules of signature campaigns will inevitably change someday. Only managers have the power to change the rules (if you don't like the terms of the signature campaign, you can refuse to participate), but changes tend to lead to both positive and negative consequences. I would like to believe that the new course in signature campaigns will nevertheless lead to improvement. I wouldn't want the forum to turn into a spam dump. For me, this place still remains a place for receiving invaluable information, communicating with interesting people and exchanging alternative opinions. In the spam stream, it's not so easy to find all this, raking through a pile of useless posts.
