Yes, you can have an anonymous account and earn in this way without, theoretically, anyone finding out your identity, but the world of technology has proven that information can be transmitted very quickly, and there is no way to be 100% sure that no one will never know that you are the one in those pictures. In other words, it is best to take any “potential” risk, even with a 1% probability, so that you don’t suffer more afterwards. Certain professions are incompatible with such a job, and you should consider that for a probability of 1% (or more) because of this occupation you will no longer be able to work in that profession. Only you can decide if it’s worth it or not.
