It’s one that many people considering this route ask themselves. Personally, I think it can be a useful strategy for giving a new account a bit of initial momentum, especially when you’re starting from zero and want to establish some social proof. For those who are curious about exploring this option, there’s a helpful overview at https://www.theyeshivaworld.com/news/general/2441992/top-7-tested-verified-sites-for-buying-instagram-follower.html that breaks down some popular services. The key, I believe, is to use such services as a temporary boost while focusing the majority of your effort on creating quality content and building genuine connections. I’d also be interested to hear if anyone here has first-hand experience with any of these providers.
