@Melissa304 you can find many instances of folks having bad info on their profile. First everyone was from NJ, then it was OK, who knows where it will be next. So, the not right "where I'm from line" isn't maybe a big deal (but I ask for guest ID & address, so I can check all that myself) and I've had people say "oh, I used to be there, but now I'm here." So, the biggest red flag is the "you can't read" comment instead of something else reasonable. Can't hurt to ask ABB to confirm, surely they know in what currency they were paid, where the internet originated for the reservation, etc.
But people are strange. It's your home tho, so ask the questions you need to to feel comfortable.
FWIW, these are the things that can sometimes be figured out before guests arrive... "so, glad you're coming to stay with us, we haven't had Italian guests yet, what brings you to town....."
