See diff above. It allowed an anon to add links to blacklisted site, but refused to accept my changes when I attempted to edit another section seconds later.
Could this have been a transient error in communication with Meta?
If the domain was blacklisted at Meta and there was an error retrieving the blacklist then it might fail to prevent additions of those domains since no regex fragments (or only some of them) from Meta were retrieved properly. If that's the case, then the cached copy should be kept until it can be confirmed that the "newer" copy from Meta has been fetched properly. This would allow the global blacklist to continue functioning (sorta - no updates are possible, but better than nothing) if there are errors getting the new copy.

I guess, this example is not valid for there was no _link_, just an url in the source code.
Anyway, the other examples seem to be valid.
