Zendra's post reminded me that our internal content search system does return more results than the NG search, which looks for complete words more than words inside of names, such as "delete131r"
I ran a search for "delet" and removed around 300 submissions.
I followed up with a search for "remov" and have removed another 70 or so.
I was careful not to delete stuff that wasn't intended to be removed or deleted, too. :)
This should help clear things up quite a bit! I should have done that sooner... But you guys have still been posting a ton that don't even have those words in their titles.
