Facebook: the dirty side of cleaning up.

I like factual programmes in fact, they're my preferred viewing but sometimes ... just sometimes, facts are a nightmare.
I had some waiting to be viewed on iPlayer and last night I viewed The Internet's dirty secrets: The Cleaners
Uncomfortable viewing for many reasons including it's political stances and references to Trump and Brexit.
The cleaners clean so we (supposedly) don't have to.
I leave you to make up your own minds.
Facebook say they they only deal in maths but that statement, in light of the programme, doesn't add up.
