Only if they've been bad. I actually haven't gone out of my way to hit rocks lately. I only do that now if I need material or if I'm visiting an island. I don't want that Nook Mile Ticket to go to a complete waste.
I only bother if it is a nook miles+ goal. Otherwise I usually don’t. But I wanna try and move my rocks to one location in my town so that it makes it easier to do once a day in one shot. Then maybe I will again
I hardly ever anymore. I get more than enough clay and iron from balloons, and I've crafted all the stone things I care to craft for the most part, so I just pick up my daily stone and that's usually good enough. If I am low enough on stone to warrant it then I'll do a little rock hitting. Typically I do it on mystery islands while I'm already collecting other resources. I'm not really looking out for gold all that much, but I'm happy to take it when I get it.
I basically only hit them when I decide they're in the way and I let them spawn somewhere else. The only place I hit rocks other than that is on mystery islands when I'm island hopping a lot so I can collect stone!
