I don't think Inco and Fro are "competition", having to use several alt accounts to boost a 16 win streak and still taking hours to do it is pretty bad (especially late at night when the rooms are mostly empty)
Jimbo VPN'ing also isn't competition
These players all got banned on their own accord and deserved to be banned
BTW when I say they aren't competition I don't mean they are all bad sparrers (Jimbo probaby is) but thinking they are competition to someone like Thall or David to the point where they would go out of their way to have them banned is pretty far fetched, they got banned for being annoying and lashing out and breaking the rules while doing so
