Wow! Thanks for sharing!
Our main selling point is focusing on quality. We don't allow Twitter accounts that have fewer than 100 followers (to filter out new spammy accounts).
Also, all the submissions are manually moderated by us. And you can customize your dashboard to only read and share topics you like. This should guarantee you are only sharing relevant and high-quality stories!
We also have community-driven tools (like "Report" button, etc). There are sharing history and reports for you to track who shares what.
We are also working on more features like click reports for you to monitor the affect.
Plenty of features are still underway and I am sure, we'll come up with even more features if / when we come across spam issues. We'll be fighting for the quality of the resource, you can be sure of that!
And thank you, Mozzers, for your continuous support of my projects! I love this place!
