Because you were posted on a thread which has been trashed now. That's why you didn't get any notification if your posts were deleted.
does seem like the case,but not the recent ones-checked the latest three pages

since my total posts count dropped and the weekly payment is calculated based on the difference between the previous week's total post count and the current one...
p.s. never mind,I'm stupid,posts have timestamps
