Novel idea here, Vanilla on the SRK boards started a wall of shame blog for Street Fighter 4, to try and pinpoint the rage quitters.1. Pictures of offenders is required for proof.
2. Acceptable proof of poor losers can be disconnects, hatemail etc.
3. To qualify as a disconnecting, the loser must pull from the match at an unreasonable time such as right before taking a loss. Everyone gets randomly disconnected at one time or another, please take this into account.
You can send this stuff into badloserwallofshame@gmail.com.
