This has been happening to me too over the last couple of months, all have the names Selena, Natalia, Brenden and Heaven, some have same last names, all of their rez dates are may 2009, all have blank profiles, I have reported many of these to LL and they do nothing about it, they have shown up at my home, one showed up an hour after I moved land, they show up at my club, at random clubs i've visited and at yardsales, I've IM'd many and they never respond. Just wish I knew whattheir purpose was. Am happy to see it's not just me and a couple of my friends this is happening to, but LL really needs to do something.
