CNN Money:

Facebook (FB, Tech30) is blocking any link to Tsu.co on every platform it owns, including Messenger and Instagram. It even went back and deleted more than 1 million Facebook posts that ever mentioned Tsu.co, making pictures, videos and comments disappear in an instant.

You can type the name “Tsu,” but you’ll be blocked if you write “Tsu.co” or post any link from the site.

Facebook claims Tsu links are spam that are annoying the community. Tsu thinks Facebook is a bully trying to kill off competition.

From Facebook’s point of view:

Tsu is a tiny new social network that claims to share its advertising revenue with its users. Unlike most social media sites, including Facebook, which keep 100% of the profit from the ads displayed on your page, Tsu only keeps 10%. You keep 45%. The chain of friends that invited you to Tsu split the rest.

That means there’s a financial incentive to post on Tsu, invite people to Tsu, and direct people to your Tsu page. There’s even incentive to send people to the Tsu pages of the folks who you brought into the Tsu network.

Your Facebook feed could easily be flooded with Tsu.co links.

The question here is, is Facebook protecting its users from spam, or are they taking action to prevent a potential competitor from gaining a foothold?
