I have had several GMs called on me while pinning mobs, and my account has zero infractions against it. People with a certain moral slant would have you believe it is a bannable offense, and inherently evil. The first is obviously not true

Current Known Issue (Oct. 14)
As of Oct. 14, 2010, we have confirmed the following issue. Investigation and recovery work is currently underway. We ask for your patience in this matter until the issue has been resolved.
- In Abyssea - Vunkerl (I-8), it is possible to abuse aspects of the terrain in order to immobilize certain Notorious Monsters, enabling players to take almost no damage in battle.
*Although the utilization of terrain in battle in itself is not a violation, abusing terrain in the manner described above, in any area, is considered a violation of the user agreement and we ask that you refrain from doing so.
*Updated on Oct. 19, 2010 at 9:25 (PDT) to prohibit terrain abuse in any area.
Thank you for your understanding in this matter. http://www.playonline.com/ff11us/polnews/news19874.shtml
