If you can login can't you remove all you information for now?? Because then people at least won't find your last name and pictures. To close your account (in case you haven't found it yet), on the help page it says you have to go to support and then request to close your account, might take while though before it actually is removed. You also might want to message a mod, because then it's more likely that your last name will be removed in the posts here!
I didn't see anyone slut shaming, but alright. I don't mind if it gets removed but then someone should at least contact mikan (would this still be breaking the rules?) so she can remove the information/page herself, because I also found the site at the second page of Google.
