[csharp]

Apples rules are a huge pain. Exception handling gets extremely complex (block all urls matching regex R, on domain B and C but not on subdomain D.B). I have not seen anyone yet able to handle the full breathe of the EasyList format.

To get around the 50k limit added by Apple, you must use multiple lists, however domain exceptions must be included in the same subset as the parent rules, since rules do not combine once compiled.

Also, dynamically whitelisting a domain is annoying since you must remove all of the lists form the webview before loading the page. HTTPS-Everywhere is even worse to get operational using Apple's content blocking lists.
