Facebook users who attempt to post links from social networking site Tsu.co to their profile or messenger will find their comments blocked, according to media reports. Tsu.co is a small, invite-only social network, whose users get financial rewards for sharing content and 10 per cent of ad sales on site. Facebook has now decided to cut out all links to the network, telling Mashable the move has nothing to do with competition, but is instead an effort to prevent ‘spammy behaviour’. This now means that anyone who tries to send a link or private message containing the link will be immediately stopped and the message will be discontinued.

Facebook took the action to ban the mention of Tsu on site, citing Tsu’s practice as spam by their social media standards by "sending bulk messages, excessively posting links ...and sending friend requests to people you don't know personally."

"We do not allow developers to incentivise content sharing on our platform because it encourages spammy sharing and creates a bad experience for people on Facebook.” However, Tsu users have said Facebook are fearful of the affects their social networking site could have on their ad revenue profits. Income from ad revenues, from which Facebook keeps 100 per cent of the profit, rose by 11 per cent for the company this year.
