Then you should go to slashdot, they have been doing that for awhile...

Doing which? Allowing multiple likes? Cross-site accreditation?

Slashdot hands out Moderation points sometimes, and asks people to meta-moderate sometimes -- both different from Likes.

For varying definitions of "sometimes."

I don't visit Slashdot anymore, but for the period between 2004-2010, I had virtually unlimited mod points.

Understood. Even then, though, you couldn't mod the same item more than once, iirc
