My mom knows, but only because of an incident that happened before the password secure room. I've posted about this before.
One Sunday, shortly after I joined the TMF, I was having a conversation with a girl in the old insecure TMF room, and forgot to ask age. The next thing I knew a "17" flashed up on the screen when she said her age. Then, a second later, something like "You are in trouble with the NJ division of sex crimes for discussing sexual information with minors" came on the screen. It said something about "Contact law enforcement, and get lawyer". I was really freaked out! Due to the fact I thought it was real, I told my mom about the TMF, in case I really did have a legal problem. Later that day, Myriads told me what happened to me had happened to others, and that the person doing it was a troll, and not a real cop.
So, due to that, my mom knows about TMF. I never would have told her had that not happened. We dont discuss it anymore. On occasion, she will ask me if I still visit the forum, and I say yes, but beyond that, the subject doesnt come up.
