So some how, i discovered that there are some forum members who are periodically deleting tens of hundreds of their previous posts/comments, supposedly for no other reason other than to keep their post count low, probably to match the number of merits they have earned, or keep their post count at a little bit higher average, what ever their main motive for doing this is, I don't know specifically, but my guess is that, they may think or consider it that other forum users, or maybe campaign managers, may consider them spammers if they have a lot of posts, maybe in the tens of thousands and not many merits earned to back that number of posts up, this is true ?
I know you said you don't want to do it, but you better name names and let's see if they are really people who delete their own posts for certain reasons or if they are surely deleted by the moderators. The question so in abstract does not give for much, but the idea that you carry I think we are goin to tell you that it is wrong, as those of us who commented already did.
