I've just had a text message saying "I believe your email has been hacked, squire." it came from 'phone number 447722663346.
I don't recognize the number (Google tells me its a UK mobile.)
I don't know anyone who would call me "Squire".
I don't know anyone who would send me a message like that and not identify themselves.
a) Delete and ignore it.
b) Leave the country and get a job as a lavatory attendant in Madrid.
