Anybody having problems with bitcoin fog?

This is like HYIP
when i try to open the website, that say is i need tor to access. I doubt, this is site scam.

Nope it is not a HYIP but a mixer.
Basically you deposit your bitcoin in a mixer, get bitcoin in your other address after fees, and no one should be able to link the two addresses.

Doesn't blockchain.info also has a mixing service?

In the past blockchain.info has a function called "shared send" that worked exactly like a mixer. But later it has been removed.
The "shared coin" function now on blockchain.info doesn't work the same way. You can read https://bitcointalk.org/index.php?topic=325594.msg3697300#msg3697300 if you are interested in the difference.
