Notes:	fixing the part about recent contributor.. <nixeagle> No, that was the intended logic, to test whether the user is The Only contributor. Putting that back. Deleting from a page you created should be fine, but blanking from an established page just because you edited it previously generally would not be. - Dragons_flight Restoring Prodego's edit. - DF Thanks for the talk page note DF / Don't trip if it is a full blank, overlaps with filter 3 -Prodego Changed from "new editor" to "non-autoconfirmed editor" for clarity. -xeno optimizing - Hersfold I increased the threshold to -2000 to decrease the number of hits - Ruslik0 Fixing the recent contributors thing; this is a string of up to ten users, so != doesn't work. - hersfold exception for 69.226.103.13 - Cen NO!
