Something very similar happened to myself (2nd in command) and my FC leader, where a long time trusted member cleared out our chest of some VERY valuable mats and defected to another FC. Not sure what spurred this all on but it was reportedly some kind of infighting between our Officers in the raid Linkshell and neither myself nor the FC leader were on to witness it. We had to kick just based on the theft evidence, neverminding the other stuff. They then took to Mor Dhona (back in ARR this was) and began shouting all kinds of nasty stuff about me, and the other members. A close friend tipped me off at the time so we ported there and began screenshotting the whole mess. I warned them in /tell to knock it off or I'd report but the response was to copy/paste my warning in /shout. I did report, SE never asked for any evidence as they had chatlogs I suppose and the offender got a temporary ban. The end result of this was a slow spiral of death for the FC as neither myself nor our leader had any heart left for it. They eventually past leadership on and everyone left. So ya, circles within circles...Don't take it to heart, a**holes exist everywhere
