Yesterday, my total posts is "82" and today i see my dp account in the morning so my post is "79". What is mean this ???? Anyone Suggest...
some threads may be deleted where you have posted. so it happens. it is not like your posts only deleted
I think it is obvious that some of your posts were deleted. It was either the threads you posted in got deleted, your individual posts were deleted or a combination of the two. No one except mods (and you, if they left infractions) can tell exactly why. You're back up to 96 at the time of my post though, so it doesn't seem to be a big issue. It's all part of the day-to-day here at DP. On that note I don't know moderator practices here (soft delete vs. permanent delete), but if you had made a post you thought was very useful and should have stayed, you may want to contact them with your case. Just make sure not to waste their time!
Like some others have said, either your posts were individually removed, or threads in which you have posted have been removed or archived. I'm pretty sure archiving a thread removed the posts from your post count, but I'm not 100% sure.
