While few of us will disagree that the prone spamming and any use of macros is a pile of steamming shite, when playing at any sort of competitive level you will meet teams who bunny hop and use any advantage (within the game mechanics) to win and thats fair enough, they aint cheating. So, you can either accept it or play like a gentleman. Playing like a gentleman will not do you any favors in a clan match in though.
So in summary, while it may be kinda 'lame' you gotta get on with it and play like how you can.
