Back in the day, there were sites that allowed people to purchase followers and likes for Twitter and Facebook. Unfortunately these sites caught on to it, and mostly stopped it.
Back then it was useful, that was until rules and changes came. Now days, if your following is bought, you're not going to in turn have real views on your accounts. As well, some sites even can check if you have a real following or not, and if you have a fake following, you could potentially be called out and could also be banned.
I used to use these methods back when I started working online, but today I would advise against it, as buying likes and followers usually results in dead accounts following and liking anyway, so it's not even worth it.
