Our ISP may switch to comcast, and I saw that there are a ton of different parental control options.

For all I know, my parents are monitoring what I do online as we speak, but I have a bad feeling that they might start using them once they know they're there. (I'm 15).

I don't do any raunchy stuff online, but I don't feel comfortable knowing people are reading my logs.

If they do decide to do it, is there a way to completely block them from monitoring anything?

I'm pretty tech savvy.
