Can you ever get delisted? Nice rhetorical question trying to lead the audience to bias against the WWPA. Yes, all you have to do is reach out to Pistos. On tangler or on the new weewar forums. Pistos always responds.
The one where someone was trying to get un-greylisted, they ended up admitting to booting someone that was just barely over the time limit because it helped them. Look on tangler for the evidence. It is a big thread.
The WWPA exists to help others keep the very bottom of the players group out of your games, if you choose. You can go all in with someone greylisted, just don't be suprised when they boot you for being 1 minute over.
