Alesana, I just met you recently in the game. You have a good sense of humor, are fun to play POTC with, and seem to be a good person. Unfortunately you made friends with someone who craves drama at other people's expense. Online friendships are what I refer to as "situational friendships", you're friends because you both play the game, and you don't know this person in real life. Online, anyone can pretend to be whatever they want, this person has proven they are not worthy of your friendship or of any of your friend's either. Your real friends do not care what vicious rumors this person spreads, they are your friends and they will have your back no matter what. If there are things you don't want to share with the virtual world then assume these virtual friends may not be exactly what you think and keep your secrets to yourself and friends you know in real life.
Don't let this person spoil your time here, I think you enjoy MyVmk and it gives you a break from your real responsibilities. We all play games to relax, have fun, and forget (for a while) other things in life. Ignore this person and ask your friends to do the same. If they continue to bother you take screenshots to provide to staff so they can deal with this person. Ignoring them removes the reward to them for causing the drama, if you and your friends ignore this person, they will stop. I happened to see you talking to that person so I know who you mean, I don't know you that well, but I'll have nothing to do with that person, ever.
Keep your friends close, have fun, and don't go. Don't let this immature person win......
