im sure they received a cease ad desist from instagram and facebook. all sites have been being hit with these
highly possible
OP: even if you comply with fiverr's TOS, you clearly violated the TOS of those social networks, so you shouldn't be surprised, not even for a second, because of you got shut down
if you see others doing the same, it doesn't mean shit (they don't push volume, they have the protection of the fiverr staff, they will be the next one who will be shut down, you're unlucky etc.)
i'm always surprised reading these kind of threads where OP abuses sites, using bots, automated methods, violates TOS and OP ends up getting butthurt when he/she gets shut down, really?! sometimes you just can't get away with it, it's part of the game
to the guy who said above that he got scammed by OP: it's pretty hard to believe if you 2 used fiverr to do business, because they always side with the buyer even if the seller delivered, it's almost impossible to get scammed on fiverr as a buyer
you have 3 days after delivery to review the order which needs to be enough time to make a dispute/refuse the delivery and even after that fiverr support will help you
if you still managed to get scammed somehow, sorry, but i need to say that it's your incompetency, lack of due diligence (ordering a service what can hurt your business even if the seller states the opposite)
or you 2 have done business outside fiverr
to OP: you said you advertised your service elsewhere, so it seems you don't rely on fiverr, you should be able to replicate this leaving fiverr out of the picture keeping in mind that you can get hit with a C&D from those social networks anytime if you grow big enought to worth the hassle for them
i'm just wondering what will fiverr do with OP's revenue, do they refund the buyers even after completed orders or keep the money as extra profit?!
but taking suggestion
