Here's a fact: Wikipedia stores the IP addresses of anonymous users.
Here's another fact: all of the web traffic from the Houses of Parliament is sent through one of two proxy servers — which means that every anonymous edit to Wikipedia from within Parliament is attributed to one of just two IP addresses.
I'm sure you can see where this is going.
Not really. I presume it means those two IPs are tagged, and no matter what kind of COI stuff comes from them, they'll never be blocked. Sort of like the nation of Qatar. It's a permanent SPA-for-free card.
