They went through a phase of this a couple of years ago (i peaked over 150,000 views on the first video diary when they bumped it off) but I thought they had given up this kind of awful censorship.

Far more common recently has been the copyright infringement reason - are you sure it's not that you're suffering from?

Anyway, I suggest you open another account in another name (with different e-m) and copy all the videos onto that as a backup.

Then, if they do close one account down, the other can take over.

And I suggest you retitle the existing videos - that confuses their system without losing any views.
