Many players are unaware that many of the top 10 to top 50 guilds are beginning to share information about players who join for a war then do not contribute points, declare recklessly, or otherwise act detrimental to the guild.

I'm giving a heads up for people who think they can get away with it. You can expect to be barred from other top guilds, even if they are rival guilds.
