No, buying Facebook or any type of social media likes does not means it’s going to be a problem for you. If these likes are real than you are 100% safe. During one of their interviews, they had stated very clearly that inactive accounts would be banned. Facebook will stop promoting your account if it notices a high number of inactive users on your page. You will thus lose the value of your account in case if you are buying likes by bots. While Facebook won't harm you directly but it can ban your pages and accounts.
