I had an issue with a dodgy councillor
Searched for their mobile number in Facebook and Google, popped up showing multiple companies and one of those was run from their home address which linked to various other companies.
Ditto searching for their email address or name. I found whilst going into a page wouldn't show the info I wanted but looking at images etc showed info that wasn't available
I'd also check companies house and look at related companies and other directors including those that have gone bust. Many create their business using their home address and then switch to a business address
Managed to get all 8 local councillors to resign en-mass and it made the MEN
