 27866.diff] uses `stripos()` instead, which is case insensitive. I have
 not dug too deep on what else could be affected by this yet.

 In case the downcasing is related to MySQL searches, MySQL's `LIKE`
 operator is case insensitive, as opposed to `=` and `IN`. It might be
 worth fetching a list of candidate sites using case insensitive matching
 in MySQL, and then using case-sensitive validation in PHP.
