When ~~~ is a username, null edits will cause recursive expansion of signatures.
More than two consecutive tildes should be banned in page titles altogether. There will be obvious brokenness if that's allowed.
An alternative would be to not expand ~~~ if it appears in a [[link]].
Still pretty fishy. Consider trying to refer to such a user precisely, you want to type out the link every time?
Fixed in r20274; be sure to run the batch validity checks after the update goes live to weed out remaining bogus entries.
