I think most people know that if a deposit is asked for, then it's probably a scam, and you don't need to spam the information multiple times.
In my experience, it usually goes like this
• Arrange meeting
• Meet provider
• Pay provider (often with massage it's pay after)
• Engage in agreed service
• Leave provider and write a review
If prior to a face-face meeting, a provider asks for a deposit / pre-payment etc
Then I'd probably just block them and write it up.
The only exception is maybe a taxi for a provider to my hotel, but usually I'd expect and agree up front in the arrangement.
