Hi Enam,
Guillaume here, one of the founders of Scoop.it. I of course concur with Nakul and would add that Scoop.it links are no-follow links which is also an important point.
We're also very attentive to not letting spammers or bots use the platform (you need a legit social network account or clear captcha to create a Scoop.it account). In addition to that, you (or any users) can also flag Scoop.it pages that you feel are suspicious or present unnatural activity. If they are breaching our terms of use, we will immediately take them down.
Feel free if you have any questions.
Guillaume
