There would be endless debate and continuos appeals etc on this issue. I agree diving needs stamping out but probably via a more workable solution than having every incident revisited and judged after the match. Could get very messy! They need a well thought out directive, this decision felt a little emotive and hasty to me, and a precedent would have been set if the ban was upheld.
Feel free to close mods, as it was posted on the video evidence thread a few seconds before I started this. Can't work out how to do this myself
