I think that it is too difficult to determine what is leeching and what is not so I see two possible solution: 1) The first way is to permit leeching only if you finish the game (like Bugfinder' s record on Psychic5)(posted 9380 days ago)2) Create two entries for games with leeching like psychic5 and psychic5-leeched so if someone want to transform a game in a marathon game nobody will take damage of it.
