She's not worried, it's likely just more BS, if she was worried she wouldn't keep working, and would have pulled her AW profile, after all if it were true the fact of strange men arriving every 15 mins for a £45 blow job would be alarming the residents (if they had notes posted through their doors)
As for legality, she is of course in breach of her tenancy and lease, and of course if she does duo bookings she is running a brothel, which is of course illegal.
