For the past several years, 99% of our accounts and our videos have not been removed by zootube, baruch Hashem. The last time zootube removed large numbers of our accounts and our videos was in 2007-2008.
I think zootube may have changed its policies about taking down so many accounts and videos because of competition from facebook and twitter. Zootube was the biggest source of information and growth on the internet until facebook and twitter came along. Now google-zootube is trying to compete with facebook for audience. So they may have become less fascistic in their censorship. It's just a theory of mine, I could be wrong.
If you want to play it safe, you can create many accounts. This is what we have done. Because sometimes zootube does remove an entire account.
