I am based in the UK and I have run the opendomesday.org website as a free, non-profit history site for many years.
When I originally built the site, about 8 years ago, I registered it at domesdaymap.co.uk. After a couple of years, I decided a .org domain was more appropriate for the project since it is non-profit. For several years I paid for the .co.uk address and redirected it to the .org address.
In about 2016 I decided I didn't want to pay for the .co.uk address any more, since all it was doing was redirecting, so let it lapse.
Now I find that someone has re-registered the http://domesdaymap.co.uk address. This is not in itself a problem, but the problem is that they have set up a mirror of all my content there.
What can I do about this? The copied content has my name on, and people are contacting me to tell me that the content is broken (which it is).
I don't mind someone else owning that domain, but I do mind my content being on it and being broken.
I have tried contacting the registered owner of the .co.uk domain without success.
What can I do?
