Question Users notified of new topics even when not subscribed

Somehow we got negative post counts again for about 7 users. I had forgotten the recommendation to use the "Recount Statistics" tool in the thread above, so I edited the raw data again using phpmyadmin. I simply removed the "-". The values got switched back to negative a day or two later, but the absolute value of post count stayed the same.

I used the Recount Statistics tool this time, and the post count went from -26 to 8. I tested post creation and deletion by creating a bogus post and then deleting it (all as the one of the users affected). It seemed to track the count accurately.

FWIW, the raw data was showing -21 the first time it happened (since the fix), so I just deleted the "-". When the issue came back the next time, the count had gone to -26. I only got notified about one post being moderated, so I don't know whether the count jumped by -5, or whether there were 5 creation/deletion events by the user, and only the last of which triggered the sign reversal.

I just searched her posts, and only found 7, though I know she has posted more often than that. I'll ask her whether she has been removing posts. None of the other users have ever done that, so it didn't even occur to me that she might be.
