I have an absolutely lovely regular client. Never a problem.
The only thing that bothers me is that he keeps changing emails and AW profiles.
He asks me to leave him feedback - it usually takes me a while before I get to do this and then the profile is gone.
Rince, repeat. He might have one other feedback form another provider. Then the profile is gone.

He doesn't change his mobile phone though.

I'm suspicious when clients change mobile numbers as it's never a good sign but AW profiles? What could be the reason?

Generally my experience has been multiple account changes = problem client.

Exactly!

I'll ask him and see what story he comes up with.

From my experience a problem client, The guy that kept doing this ended up turning into a nasty guy, Sending abuse texts from 4 different phones until I warned him I'd report him to the police for harrashment. My crime was I didn't answer his endless text.messages over the weekend and he put letters through neighbours doors saying I was a prostitute, Luckily my landlord was understanding.

This guy didn't start if nasty, They never do but red flags start to show.

If they keep burning bridges with other girls then they keep changing AW accounts because they get blocked.

Be careful,  Don't give away any details to this guy about anything keep vague.

Good luck.
