This has been discussed before on this forum, and I personally feel that some people are too sensitive about what is "dirty". If you are referring to cranking submissions before your opponent has a chance to tap, slams, small joint manipulation, biting, eye gouging, and other things that are clearly against the rules of any gym and/or competition that I am aware of, than that is dirty and totally unacceptable.
On the other hand, some people get very sensitive about leaning on the throat, digging an elbow into the ribs, etc., which I accept as part of the game. It is a contact sport, and some level of toughness should be expected. Also, anyone with a more catch wrestling oriented background knows this is SOP for those guys.
