"And BPIP indicates that you had 273 deleted messages (and probably many more). After a while, don't be too surprised."
As for the news, I delete it because I have been working here for almost 4 years, I received a lot of news, but unfortunately most of it is from scammer.
If messages are understood as posts, I delete the last bump post as it adds a new post.
as far as I know, posts you deleted on your own do not get counted on bpip. if you checked the bpip again you'll see that it says "Posts deleted by moderators" it means posts of yours that were deleted by moderators only and not by you and the moderators.
