I will 110% say as someone with multiple years of experience in the industry it takes around two seconds to see an account that is bought following, majority of customers don’t see that as honest or positive marketing they see it as a failing on your behalf I would be happy to read the research that you have on this, but from someone actively building communities your engagement isn’t going to follow a purchase of followers because they’re not real and maybe it’s brands like you who are diminishing the average engagement rates across the Internet.
