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, ]/quote]

That's really insane if truly some users were found in this kind of mess, which could also indicate many things such a user should be suspected of aside the reason you gave here from your perspective, what i see that might have led to this kind of action or when a user is trying to engage on phishy or dirty acts personal to him and use that to serve as cover for such nasty behavior, maybe when the user bought an account which posting styles strongly indicate a change of hands or the user has been spamming the account with useless posts and want to be serious about it, but either of the ways, it's a bad idea to delete post one has already made over time except for suspecting reasons from any user.


Best known to th any of the reasons which i think none is valid enough for taking such behavior, i cant build a profile with my deliberate consciousness and think about deleting them, there's no reason for any justification on that for me, if i see a user that does such, I'd rather be careful and avoid such.
