As you may have learned already, Amos Yee's YouTube channel is blocked:

The problem is, he is not the only one who is being gagged by the YouTube. "One Life" and "Shaun TV" pro-MAP channels were also blocked recently:

And a bit earlier, "Nucklear ProtoSTUNT" and James Carter's channels (the latter being the last persistent remainder of the Heart Progress) were blocked as well.

It seeems that YouTube has started a big anti-MAP purge...
