Broken games - temporary ban until they're playable.(posted 9583 days ago)Two players required - probably no point in having them there for leaderboard points.
All other games - leave them there. If they're that easy and someone is really interested in the 100 points so be it. I personally haven't been bothered trying to find them and if I'm ever worried about unfair advantage there's nothing to stop me spending a day or two to get the "perfect" points along with everyone else.
