I spoke with Matchbook about the parasites who keep putting up offers to buy the team way ahead at 90-1 and such prices and they said that any member who does that will be warned and then banned if they keep putting up those "opposite lines".
However, it seems like every single game, these parasites continue to do it and it really is a hinderance.
I encourage all players who use Matchbook's live betting feature to email
mclancy@matchbook.com anytime you see these "opposite lines" being entered as he did tell me he will take strong action against any member that puts up those ridiculous lines.
