At the risk of causing more bristle, I will say that yes sure, you can ban anyone for any reason - but I do not go around telling my friends, family, or someone I meet on the street "I can ban you anytime for any reason I choose, or change your name from a male one to a female one" (for example) If you did that there would be constant anxiety and lack of trust. I do not think this user had you in mind when they named themselves.
Yes, but this is a business situation where a service is being paid for. This is not a friend's or family situation.
If a model wants to clearly communicate and warn members what kind of behavior gets a ban, then that is a noble, direct thing to do. It sets clear expectations and boundaries. If an individual has an anxiety disorder, or issues with social anxiety/ anxiety talking w women, that is for them to handle with mental health/ a therapist. Not for them to be projecting and putting on to a broadcaster, to be responsible for handling.
On the site that is my main site, men come in
nightly new to cams, asking for the rules/ guidance.
Again "anxiety and trust" this is a transaction, not a long term relationship. Your post seems really out of context to me, and way off base.
ETA; Yes, for anyone reading this; if you are thoughtless and rude, and put in 0 effort (even though it's online) some people will still directly note that, and call you on it
Or, in my personal case, straight up decide you are a huge turn off, and ban you from the getgo (for clearly being so oblivious that you'd end up being more work than you were worth, in a business context).
