I believe you, I found diggum's report on it..... It may have been removed by an admin, the only threads or posts I delete are duplicates, I keep all others and do a soft delete so members can't see it or move it to quarantine forum.... Most other mods do the same, I am checking to see if anyone knows what happen, thread is gone, I can only find the report....
Just for the record though, we are not required to tell anyone when a thread or post is deleted, any thread or post can disappear at any time for any reason as per our TOS.... But with that said, your thread should not have been completely removed, we keep them so they can be restored if needed or if a member goes to admin and says "I never said that" we have a record which has happen in the past.........
Even though I did not delete it my apologies because it was deleted....
