is there a Yahoo Sandbox?

I have read much about the legendary Google 'Sandbox'. I am quite new to Search Engine work but am learning as much as I can . The sandbox is where a new site gets a penalty for a period of time for being young and too pushy , is that right?

Well I have something for Google ---> YOUR ARE AGEISM DISCRIMINATING and that's against all the rights! There is nothing wrong with young.

Now that little rant over I want to know does the same sandbox system operate on Yahoo?

I've never heard of a Yahoo Sandbox,as yahoo is a search engine it must have the sandbox.website can be put on a sandbox if they are doing black hat technique.
