Just like access to any other adult material, guns, alcohol, porn; adult rated films, music, games and other material a parent has a right to monitor & limit access to adult websites, blog content, videos, and possible people (just like where your kids go and whom they speak to in life) posing as someone other than whom they claim to be.
One is NO DIFFERENT than the other.
It is not a parent's right to do so... it is their obligation... if they do not, they are lacking in parenting skills and, well, you can fill the rest in.

Monitoring is control. If you can stop something you don't want, you have, in effect, already done so.
