There is definitely a difference between writing nitpick reviews and writing negative reviews of a place based on legitimate issues. If you leave negative reviews complaining about finding a hair on the carpet then yeah good hosts probably aren't going to want someone who is that much of a nitpick.

But if you leave a review complaining about real issues like no towels, dirty sheets or bathroom then that's not going to hurt your chances with good hosts. Believe me I've left a bad review based on an Airbnb place being dirty, and I've left a neutrally toned review that complained about some minor issues like a slightly dangerous ladder leading up to the loft bed at once place I stayed at, and I don't have any issues getting great Airbnb places.
