Post bursting have been of major concern in the forum and I observed that most of the people that does post bursting are those with high numbers of post count per week in their campaign and newbies too and this post bursting is mostly noticed during the ending days of a campaign as some users does so in order to meet up signature post quota to get paid however, I suggest there should be a restriction that should be placed such that if a user makes a post, they will not be allowed to make another post until like 10 minutes or more, by so doing post bursting will reduce drastically but as for spamming, once a spammer is always a spammer so just like others suggested, report to moderator is your friend.
I don’t think the time limit is necessary honestly, we all see post in a different way and we reply with our different view for example, a user can read the op and still go ahead reading comments that’s normal meanwhile some threads don’t deserve much attention and it’s not a must to reply, like sometimes I get busy and I intend to make post after then at the moment. If I should follow this pattern I observed I make post after getting full detailed of what the op is referring to, if the whole thought is coming from campaign post count I kinda disagree because most users are not in a sig campaign.
