Facebook is blocking all mention of Tsu.co on every platform

Coincidentally, this is also a good measure of the lock-in facebook has. If no one hears about this it means facebook has achieved a certain level of control of the amount of information people get— they have in that case truly invested successfully in 'virtual reality'.

Their model is to spam other platforms with a referral link, it's reasonable that they're seen as spam by another platform and then blocked.

Facebook in my experience does a great job with tge advertisements not being too onerous and not having too much spam. Spamming Facebook with tons of links to your social network site is not a legitimate advertising tool

This is very intriguing. I think a platform with a business model that effectively remunerates users is what it will take to kill facebook.
