Wow that is just crazy...
I knew the guy pretty well at some time, about two years ago I think, when I was leveling my RNG and was trying to do my first 5-2 mission to get Rank 6. I had this friend PLD 75, Mujahid, who looked so cool and powerful at the time because he had helped me to complete Genkai 1. The guy was rather weird and lunatic, some sort of gothic kid offering Red Roses and writing poems to female Elvaans... One day, he told me he was doing the mission with Shealia, a WHM 58, a nice girl I had already met in the past, with who I kept touch from time to time (and the one who apparently wrote the post on Allakhazam).
Then we all went our own way, me leveling my WHM because I had stopped my boring RNG at 74 and him was starting his NIN. Few months later, I was camping Simurgh, with a friend I had met in WePoke, Xyu (can't remember his main character's name, he was a Mithra RNG, brother of Alexandor and Ochocho) and saw that Mujahid was hanging out with the old Gil sellers crew (Element I think was the name? That Elvaan female NIN) and decided to never talk with him again (God, I remember these days when I was taking the game so seriously...), as the sellers were so powerful at this time and would ruin any chance to get anything.
Then the guy disappeared for another few months, and when he came back, I talked with him for a bit, and he said that he had worked with the sellers because he had lent his Scorpion Harness (worth a shitload of money at this moment) to some guy, who had borrowed lots of items from lots of people, and had moved to another server (can't remember the dude's name, but I know it had made big drama cause the guy had scammed many people) and wanted to do anything to get it back, even if it meant working with the sellers. Anyway... Never really talked to the guy after that...
Everything to say... You really never know people, be it your real life friends who will betray you in the bad moments, your neighbor who have plans to bomb a mall, or people you think you know on a game with who you have touch in the real life...
