Does Facebook approve personal loan offers?
What about fantasy sports (that pays real money in the form of prizes) like fanduel?
There's nothing specifically bad about personal loan/financial stuff but I imagine you may struggle to find legitimate offers on affiliate networks.
You should check the MyWoT ratings of these offers before even considering them. Unless they are from legitimate companies e.g. Chase, Bespoke, etc. then they will probably be from really shady payday loan companies, and I would steer clear of those unless you want your account vaporised.
Fantasy sports is more kosher but again, understand that if the site/offer has little integrity (will then bring user complaints) or a poor MyWoT rating, you will likely just damage your account standing.
FanDuel for example looks fine - clean MyWoT rating apart from some angry people who have been advertised it via pops no doubt, has been around since 2009 so have weathered many storms (inc being sued).
fantasy sports is considered gambling and you will not get it approved
legitimately anyways
Oh yes of course. There you go, the unicorn has spoken.
