Facebook claims Tsu links are spam that are annoying the community.
Sebastian Sobczak, founder of Tsu said: 'We're persona non grata. You can type in all sorts of seedy websites, and you can get to them. But not us. We don't exist.' Tsu claims Facebook is trying to kill off the competition. See also why do people hate change.
Tsu keeps 10% of ad profit, the user keeps 45% and the chain of friends that invited him/her to Tsu split the rest. Facebook, on the other hand, keeps 100% of the ad profit.
Facebook claims tsu.co users started sharing too much links and friend requests to its users. This made them flag tsu.co as spam although tsu.co didn't pay its users to share links; they did it on their own.
On September 25th, 2015, Facebook banned Tsu.co entirely. No messages containing links to tsu.co can be created since then.
Tsu.co had received around 2,500 organic visits each day from Facebook. After the ban, that number dropped to 0.
Facebook says it will unblock tsu.co if they make it so that their users post simultaneously to Facebook and Tsu.co.
Melanie Ensign, a Facebook spokesperson, said 'We do not allow developers to incentivize content sharing on our platform because it encourages spammy sharing.'
Many Tsu users, who are mostly photographers, models and other artists, feel this Facebook ban is unfair.
Facebook even deleted legitimate content containing tsu.co links, such as charity work. For example, Claudia Everest, a 47-year-old cancer survivor, lost 7,500 Facebook posts of charity dog drawings. See also: why you should donate to charity.
Some believe the extreme banning and deletion of all content coming from a competing social network shows that Facebook is afraid of tsu's business model.Facebook claimed their content was spam, but the fact that they offered to lift the ban if tsu.co advertises them debunks this claim .
