Hi solvegas,
I do not have a site, but today I have blocked instagram and I do not understand

Depending what you want in future, also look in blocking:
- Twitter
- Faceb$$k (I can't write the full name it might get replaced by a script here)
- Google+
- Tumblr
You don't need to use all of them, but better block them now than loose to imposters.
