The generated addresses aren't real. It gave a London address for my MP; I know where he lives and it isn't London.

Most MPs' home addresses are actually quite easy to find. Mine's was printed below his name on the ballot paper last election – a nice reminder of how we used to have a high-trust society. I doubt this practice will be continued for much longer.

Yeah the address on all the IDs is for parliament. I assume one could find em there
