Yes. Go to broadcast screen and chat preferences and scroll down. Chat preferences etc are small and top left of broadcast screen. Lots of options. If you ever plan on doing fan sites or content another one I would select would be auto record all paid sessions, but that depends on your personal goals.
Be aware they can also change their names, however they have 1 set account number for each account that does not change. Many members do have more than one account. Most don't have more than 2 though.
For instance the member I not so affectionately nickname Unabomber has 5, but I digress lol. Most don't have more than 2.
If you put a note on their profile, even if they change their account name, the note still identifies them. Most of the Members I deal with aren't gamey like that, but you'll get a lot of gamey guys starting out. Block feature is your friend. Different models have different levels of tolerance for that. I can't do 8 hour shifts, so I have low tolerance for anything that wastes my time, even in the slightest. Or creeps me out, even if its something generally acceptable to most others. I'm limited to 3 hours per day max, so I block anyone who pays low but is gamey, or time wastey, or not aware of context/ slow/ oblivious. Most other models are not that strict as me though. Your room, your rules.
There are a lot of super cool, aware guys on the site, but you have to sort the chaff from the wheat, starting out.
(I am coming up a decade mainly streaming exclusively SM, but I had to open a new account due to the collapse of a daily pay studio. So I will be showing as new with you too shortly. But I'm not.)
