Messaging on SA and screening out UTRs
Limit your messages on SA to banter only, if they start with pointed questions about any arrangement take it off line. When they come at you hard with "What are you looking for" that's a cue that they don't know what to ask for and are deferring to you. Banter will help you figure out how to come at these POTS during the next phase of things.
Rather than answering what you are looking for, tell them what you won't accept.
We all have HoeDar skills, but a good way to screen out suspected working girls and UTRs when profiles look edgy is to ask them what's on the menu. If they aren't working or UTR they will have no idea what you mean. If they are, their answer will be on point.
NON-UTR RESPONSE: "What do you mean?" You say "I meant what are you up to tonight?
UTR RESPONSE: "I am" or "200 for FS" or "What are you looking for?" & "How long did you want to see me?
