My most recent move in once pinged 4 times in a row to ask to leave lol. Then Bones pinged 4 times in a row, so I let Bones go. It was kind of insulting for the same person to ask so many times, and I felt bad making them stay. Guess I got unlucky with RNG.
EDIT: just remembered there was a camper that I invited in before the most recent one that asked 4 times in a row, so I have nothing to add lol
