Angry with entrecard

I am very angry with entrecard system. They considers my site was spam blog.
They said that because entrecard is their system and they want to do what they want.
It is not acceptable. I will make my own system which can be better than entrecard. If we have more competition, i think they will know where they are in internet.
They delete my site but all their ads is still in my site. What do you think about them? They are all bullshit.
