Hmm, if I'm not mistaken, you have to be verified in order to broadcast, even if you are on your friend's account. I know this is certainly the case on Chaturbate. This *could* connect a 1099 filing toward you, but possibly not so long as the money is 'going to your friend'.
Just be careful - playing around with the IRS is no joke. I hate to say it, but if you're a dependent, you might want to reconsider camming until you are filing your own taxes. Regardless of whether or not *you* report your income to the IRS via a 1099, you very well could have one mailed to you if your address has been filed under your verification.
I see this a lot - cammers worried about taxes because they are dependents. My ultimate recommendation is that you should wait until you are filing your own taxes to do stuff like camming, unless you're OK with your parents knowing about it. Good luck
