I know a good deal of people that delete their profiles when things get overwhelming. Professional cuddlers are often empathic people and pick up on a good deal of their client and cuddle buddies' emotions. I am of the persuasion that you should always let your people know before ghosting. I only give my phone number out once an user has booked with me. I know numerous cuddlers that have been banned because they have accounts on other cuddle platforms or have listed various ways of booking with them. It's extremely important to follow the TOS no matter your cuddle affiliation. This shows that you are indeed able to follow rules and understand consent when it comes to guidelines. If someone cannot follow guidelines, they may choose not to respect your level of boundary or consent.
I 100% agree with @cuddlefaery, @cde123, @pmvines, and @stormydaycuddle. @Mike403 has a really, really valid point as well. Do you know this person's history? If they are new to cuddling, this might be explainable by something simple. If he is not, RUN. Block and make sure this person does not have your personal information.
