Dark Patterns

I  have been in the situation of a dark pattern before. It especially happens to me when I'm Instagram. Since I follow and like a lot of makeup related pages I get a lot of ads that are about beauty. I once clicked on an ad about a facial cleanser because I was in need of a new one. Before I was even able to see what I really wanted it asked for my email. Then a pop up showed and ask me to join so I could receive there 15% off only if  I order at that moment. I felt like I was being forced to buy something immediately when I just wanted to see what the product was really about first. I find that most Instagram ads are a scam because of its cheap products being sold. The ads also look very fishy sometimes.
