That's not an active campaign signature; he's just wearing it for fun and posting to increase activity points, because I don't see any reason why they'd continue making more than 20 1-2 liner posts every day.
Any of those posts can be reported if someone thinks they are not quality or constructive posts on the thread. Regardless of the time gap between posts, poor quality posts should be reported and removed. The length and shortness of a post does not reflect its quality, but the content of what he conveys will determine it all. So I wouldn't be surprised if the user mentioned had enough basic knowledge of a few things that his post couldn't be removed entirely.

I will, but I just wanted to bring this into everyone's notice, or maybe find a quicker solution to the problem.
The user above basically already has more than 100 activity, so he only needs 4 seconds between posts before he posts another one. The problem is quality, if you think the post is not quality then you need to report it.
Limits on postingwaittime = 360;
if(activity >= 15)
waittime = (int)(90 - activity);
if(activity >= 60)
waittime=(int)(34.7586 - (0.0793103 * activity));
if(activity >= 100)
waittime = max((int)(14-(activity/50)), 4);
