Bitcoin spinners - fraud?

[jeyjey]

Lot of us are watching everything about the Blockchain world. We want to work with it and we want to explore everything. There is a new kind of fraud: bitcoin spinners. There are websites that scatter away bitcoins. It is enough to try to rotate a graphical pinner in the screen of their homepage. I suppouse that their profit will be to have the users accounts and try to empty the wisitor's wallets by copiing their private keys. What do you think about? Many thanks.
