Maybe something went awry when the mods were deleting that stupid kids troll posts. I wouldn't get too hung up on it. You fixed it, so it's all good now. Being a GM on this site doesn't give the person extra privileges to edit anyone else's posts, so unless they told the Mods to mess with your stuff for no apparent reason, and then said mod decided that sounded like fun, there's no reason to go all swears on our lovely GMs. 

Maybe you should email Mahz if it's really a big deal. He would be the only one who would be able to figure out what glitched out in the matrix, so to speak.
