In a world where your popularity is pretty much gauged on how many followers you have on your social media profile, it’s hard not to be tempted to get free followers or likes whenever you could.
While there are some good things when it comes to getting free followers, most of the time it does more harm than good because getting followers this way would usually mean you’re getting followers from dummy account created solely for this purposes. There are no real people behind these accounts and it doesn’t add any value to your “popularity.”
If a person doesn’t know you, they might wonder why you’re so “popular” so they might follow you for a while. Unless you have something real to offer, then these new followers will found out that your account is boring and not worth following. If you’re just getting likes to make yourself feel and look good, then sooner or later, other people who follow your account will see it and leave. This would make you look bad if they tell others about what you did.
