Not strictly about genealogy research but about tracing.

I need to know what tools/methods that the UK-based tracing agency Finder Monkey use to trace individuals.

It's come to my attention (can't say how as would be outing) that someone from my distant past is planning to enlist this agency to trace me. There are very specific and serious reasons I don't want contact from this person.

The person looking for me only has my email address and name (possibly might remember my DOB, but not sure). They know the city where I last lived, although I have moved away from there a few years ago.

I don't use social media (living in hiding from an abusive ex. He's not the person trying to trace me tbh, totally unconnected), and I don't appear in google searches. The nature of my work means I need to be careful about appearing online anyway.

I've ticked the relevant boxes (always) on electoral role forms to say I don't want to be searchable to the public.

I do own a property, so worried in case the agency search my details on the land registry.

My name is rather unusual.

Where else do they search? Banks, GPs etc?

Just trying to stop myself being found by this agency on behalf of the searcher.
