How do you get your name removed from the UK general election?

I'm planning to move house soon, and would prefer not to have my name and address on anything because of the sheer magnitude of morons you have attempting to dox you online. That's because of some weirdo who keeps stalking me online.

I also need to see somebody about bidding on properties, because the arseholes never bothered to change my password when I requested that they change my email address. I told them the password reset option doesn't work, as no password link arrived in my inbox. I also checked my spam folder, so it seems only they can change it on their end. So I emailed them to point this out, and they just sent another password reset link, which clearly doesn't work.
