The critical issue is cash-rich internet and major social media sites have lots of lawyers, are quick to litigate, and are leaning heavily on Fiverr to shut down providers who offer fake or bot likes. followers or other hacks to their sites. They may terminate your gigs or accounts quickly, because they don't want to be sued quickly.
Similar big corporate litigative pressure was put on BHW years ago to stop posting about BH ad postings, e-whoring, cookies and similar methods. You'll have to employ these methods very carefully to avoid getting hammered by the gig sites, or the big sites directly.
