curious about mass DMing that doesn't have to do with PPV co.. (OnlyFans)

curious about mass DMing that doesn't have to do with PPV content:
do you usually respond to them? do you see it as a way to finally respond back or do you not care because you can tell it's a mass DM?

i don't do mass DMs because i find them annoying personally so i wouldn't want to annoy you, but i wonder what the effectiveness of them are.~
