The loophole was more commonly used for reverse banking early age, and before the aid being hostile action ooo boy was it effective. The 25 man kingdoms were more likely to invest into proxies in my experience while shells like MEGA (not saying MEGA did) were more likely to use sitting re-invite. The amount of speculation around MEGA leads me to believe it was a very shady place and since I'm not looking to convict them in court that is all I need to set my opinion.

Any crown gained via shady means even if it's less shady than the competition, is a less valuable crown. You can out play the chit out of the server with a shady move and that's a cool story to tell but I don't believe that to add value to the crown.
