Is it safe to buy aged Reddit accounts for marketing purposes?

Been thinking about leveling up my marketing game on Reddit, but I keep seeing people talk about buying these “aged” accounts, and honestly I’m torn. On one hand, my fresh accounts get slapped with limits or shadowbans the second I try to post anything even slightly promotional. On the other hand, buying accounts feels kinda sketchy, and I’m paranoid about getting nuked or scammed. I’ve put a lot into my project and don’t wanna blow it over something dumb. Anyone here ever tried this route or know if it’s even worth considering, or should I just stick to growing accounts the slow way?
