Blog or Free Webspace Provider that doesn't ban quick

Hey, i need to create a few hundred blogs/sites per day.
I tried blog.de but they ban real quick, Yahoo Pulse somehow blacklisted my urls, i'm not sure...

So i need a blog or free webspace provider with many different domains where my sites stay alive for a few days.

Yahoo Pulse is working now, they banned bit.ly too...
But still need some other options.
No one got anything?

I like posterous. I've been able to keep blogs up for a while with them. Look at targethut dot com for a good up to date list of web 2.0 sites
