I have got a great idea after stumbling upon some fraudulant and fake spotify site (some of them are real but they sell hacked spotify accounts). There should be a page on Spotify's website which will warn people of fraudulant spotify websites. The page can be updated regularly with new fake spotify websites.

This page already exists and that's the Spotify Community! If you find any fraudulent website, feel free to let us know in the Help Boards. Alternatively you can send an email by getting in touch with us here.
Let us know if you have further questions.
