Don't fool yourself, before you get the opportunity to speak you might have found yourself in a deep problem. Better you have something more tangible that you're doing because being on the forum isn't a job or enough to sustain you. Have something professional that you're doing so that you can always put that in the front when you're being confronted.
I was just about to say this because if it is in the intention for the authorities to extort money from you, saying you are something that they do not understand will only land you in more trouble.
Finding a job or a skill to be involved with is the best advice still, even if you earn more from the forum from promoting projects, do not abandon any skill you have and feel too relaxed.
