Yeah MRDYD it seems like there are always 15% that rush to sign up for any tournament and within 5 minutes lose interest in it. Last year in the alt shot tourney, they two guys we played scheduled a match on 3 times and never showed up. Finally showed up and played with pretty much no excuse.
While I would rather play to win I have no tolerance for people who won't respond, schedule and don't show up, are late etc. I say if they aren't responding, report it to the tournament owner and let him send a pm or wall post to them saying they will be forfeited if they don't respond within a specific time frame. That eliminates the he said she said excuse of not playing.
It is always the same, a few bad apples can ruin the whole group.
