I didn't expect the thread to go on for so long, people kept saying 'Add this to the list' but there was no list so I've actually made one. I'll try and keep it updated until Capcom add in a penalty or fix this.
I've decided in the interest of fairness to only list the players who quit where there is an actual video that can be used as evidence. I know many of you took the time to post when you only had the CFN ID and while I believe that you are right to name them, without proof it's just hearsay and Capcom won't be able to do anything about them.
From this point I'm going to have to let the list rest as it is, feel free to continue to add posts to the thread but they won't be added to the OP.
