it really depends on the game ime. if the game allows top levels to be used for AC no matter if someone replies or not then it's more common because it's an easy way to pass AC
I find that games where this is common are busy and faster ones so it's usually the case that everyone's already got so much going on that there isn't a lot of reason to tag out everywhere as well
