This is the only special case with this linkshrink.net site I have tested, but others shortern url sites like shorte.st, adfly, etc allow to share links in facebook, twitter, google plus.

no. i just shared link in different facebook groups. I think they ban me due to low or poor quality traffic. So it is not easy to earn from this site

I registered in linkshrink.net and start to share links in facebook but they banned me in the next day due to fake/cheap traffic. So no one can earn by sharing link in the facebook on this real scam site. So beware from this scamed site.
