Good afternoon. This morning I encountered three spam pages created by newly registered users on All The Tropes. As we normally do, I went to ban the users and delete the pages. But unusually, the pages did not delete -- instead of receiving a confirmation that the page was now gone, I found myself returned to the "delete page" page. Similarly, attempting to ban the users simply returned me to the "ban user" page.
I jumped over to my sandbox, and created then deleted a page just to check if I was seeing some kind of global failure. The page I created deleted promptly and with no issues.
I returned to the spam pages and attempted to delete them again with the same results as before.
Eventually I discovered if I relaunched a delete as soon as a previous delete failed, it went through. Similarly, if I reattempted to ban a spammer the moment I was returned to the "ban user" page, it, too, succeeded. However, this is worrying behavior, and I wanted to bring it to the attention of the staff in case it is indicative of some greater issue.
