I am sure this has been asked before but I can't figure out where the search function is. My question is, are back suplexes specifically forbidden in Folkstyle? I have asked my coaches in the past, and got two different answers. One told me that they were illegal, the other said they were perfectly legal. I decided to do some research.

I know there is a "slam rule" but the slam rule is very general and doesn't mention any specific throws.
When a wrestler lifts another off the mat, it is the lifting wrestler's responsibility to ensure the other's safe return to the mat.
Further more, I have to date not found an enumerated list of illegal throws. Based on this information, if I can perform the suplex throw (or any throw for that matter) in such a way as to reduce the impact to a tolerable level, wouldn't the technique technically be legal?

Is there something I am missing?
