I will preface this post by saying this is merely curiosity, and by no means a complaint.
Why do moderators delete users posts before they reach a new milestone (usually a number of thousands)?
I noticed this as I had previously been only 5 or 6 posts away from 11,000, but am now nearly 70 posts away. I can understand doing this if a user has blatantly been spamming or shit-posting in order to reach the number, but I honestly have been posting pretty rarely and sparsely these past few weeks. I was mildly excited about 11,000 posts, but not enough to change my posting habits, so I just posted as usual, figuring I'd eventually reach 11,000 when I reached it; no spamming, no blatant +1s, no "Hey, just reached 11,000 posts!" thread to be seen. And yet, sixty of my posts were deleted today. I don't care enough about reaching another milestone to be upset about the deletion of these posts (and they probably weren't too grand anyway), but still I find myself wondering why.
Why are moderators intent on slowing down users from reaching these milestones? I've seen and heard of this happening to many users before; some who were blatantly spamming to reach the number, some who were clearly not. Why does this happen every thousand posts a user makes?
