So people have been marking a lot of pages lately, and SFWBOT is following suit and removing them. With the high volume of pages going in and out of Category:Candidates for deletion, it is very difficult to monitor them all. Mistakes are bound to be made, and some articles might get deleted even though they are perfectly fine.
This problem was expected at the very beginning of the cleanup, and is nothing to be worried about. ALL DELETED PAGES CAN BE RESTORED, so if your page was wrongfully deleted, please post a link to where it was, and one of the staff will review the page and restore it as long as it qualifies. WE WILL NOT HELP YOU IF YOU DO NOT PROVIDE A LINK.
Please be aware that this does not exempt pages from meeting standards. If your page is restored, and it does not meet standards, the page will be re-marked with the standards template and given the normal 5 day grace period to be brought up to standards. If after that time the article doesn't meet standards, it will be deleted again.
