The difficult part would be drawing the parameters of what constitutes guilt. Some people, for example, would think that leaving an RP for any reason, through any method, earns the player a black spot. I, for one, would argue that [u][b]if you announce your leave[/b][/u], you're innocent, whereas going AWOL is blacklist-worthy. We as a community would need to agree on those boundaries.

This, pretty much.

These people are the ones who cause big problems. Especially if they are -Hidden- in Ghost Mode. Thankfully through the power of adding Friends, you can root out the hidden users and figure out when they are online. And a basic look at their post history can tell you if they are ignoring you and your group or not.

When they don't even respond to being Mentioned, you know you've hit a big offender.
