You're joking right? This is the worst start to pinterest I ever read. I'm not sure they allow adult you'd have to check. And just cause you posted your link on your profile and you follow people doesn't mean they are going to say "oh yes, someone followed me let me checkout their link and buy what they are selling right away" lol and I know that is what you expected.
As a noob we all been there even the most experienced amount us. Also you posted once or something? Come on, take a look at the successful people on Pinterest. They aren't doing what you re doing, they are building up their accounts naturally over years and liking and following people, and posting thoundsnd of times over the years. You're just spamming for 2 minutes to make a few quid cause you are broke and can't think of a good business idea to market in a genuine way on Pinterest and other social media platforms. Thats why you're using cpa, you have no products of your own.
You should approach social media like a grown up. Follow the platform rules, and take advantage of the free traffic. Not get banned. Whats the point in spamming if you end up banned? Isn't it easier to just market something that is relevant and worthwhile in the right place, that people are happy to buy, instead of bothering them with spam, and HOPE they will buy? You don't buy through spam, why should others buy through yours?
