This is because when someone joins a campaign and they want 15 post and the person joins 2/3 days to the close of that week, the person tries to post all the 15 posts thereby spamming the forum with so many post within the 2 or 3 days.
You doing same thing. There is hundreds post regarding signeture campaign. You didn't read them and just make new thread. I noticed you have ware signeture also. I noticed you make 7 post on 11-7-2018. So are you different from them ?
I have visited your profile , I can't see your reply more then one line. Even you are not reach on member's rank you have joined signeture campaign. So how forum will spam free. We can't expect it if signeture are not disable up to member's rank and initial merit holders. Initial merit holder should be remove from signeture. I can't see any difference them from Jr. Member's. If anyone can't earn single merit for me he is equal to Jr. Member's.
First we need to change ourselves & our post behavior. Then we can suggest to other.
