I don't know if he's dangerous but he's definitely annoying and slippery, not sure if it's worth a warning.
 Contacted me on adultwork ages ago offering driver services, i accepted once. After that he sent constant questions, offered his house for incalls. Had a weird vibe off him so i refused to do him a booking. Finally convinced him to leave me alone. Every couple of months he messages me again asking for a regular meet, 'it will be easy money'. Calls, leaves voicemails, texts allot. Recently messaged me on adultwork again for a meet and pretended he had never spoke/met me before. Used two other numbers i didn't save (stupid) main phone number is 075700243**. Average height, short gingerish hair, 40's-50's. Lives in Bury.
