I think these things should be done away with, see jocks droping hands etc all the time and i know in alot of cases its in all innocence but if even 1 occasion is not then that alone should be reason to ban these.
Even just a couple of hundred here and there would soon build into a tidy sum for any cheating jocks but would go unseen by the powers that be.
Just my opinion but i think they are like dangling the carrot infront of the donkey :)
