Ratings System on Adultwork.

Can someone please explain to me how the ratings system works on Adultwork?

For example, some users, one user in particular has an unbelievably high rating.

And yet when you read their feedback, the high rating numbers seem to have be gained by adding up multiple feedback comments from the same person...... posted over and over again, in rapid succession, even in the same minute.

How does that work then?

Yes.... it's so I can copy them .... before anyone says it!!! :D
