 Removed requirement to sign because new users keep messing it up.
-An old user broke this by editing in an http link. The least complicated fix I see is requiring everyone to follow the rules for the page. Of course this means some edits may now require disabling the filter first.
+To prevent accidentally breaking the system, even old users are prevented from adding http links to the introduction page.
+In a (barely failed) attempt to express this without repeating conditions, I made this handy Karnaugh diagram:
+A = article_articleid != 10933
+N = !(user_editcount > 0) & action != "createaccount"
+C = (!(user_age > 0) | edit_diff contains "\n-" | edit_delta > 3000
+D = edit_diff contains "http"
+            AN
+  01  11  10
+CD  00               X
+       X   X   X
+       X   X   X
+           X   X
+The filter condition is thus N & (A | C) | (!A & D).
-if article_articleid != 10933 then !(user_editcount > 0) & action != "createaccount" else
+(!(user_editcount > 0) & action != "createaccount"
-!(user_age > 0) | edit_diff contains "\n-" | edit_diff contains "http" | edit_delta > 3000 end
+& (article_articleid != 10933 | !(user_age > 0) | edit_diff contains "\n-" | edit_delta > 3000))
+| (article_articleid == 10933 & edit_diff contains "http")
