There's loads of them now.
Often they will ask where you are so I guess they are running the scam nationality.
Sometimes I will play with them and tell them I'm in Newcastle. They will usually message back a city centre location. I'll then say 'No Newcastle under Lyme' to which they will usually message back a new location.
I'm wondering if these scammers are even in the UK.
Golden rule as always - no upfront payments
