Those WOF spins aren't related to the premium membership benefits. Freebitco premium membership benefits are broken for all the users since last few months. I had also received 10 WOF spins like that on my account. I don't have any FUN tokens on my account. Some people have also said that they received this type of email from Freebitco recently.

I did not get those spins, just checked the mail and there was no mail with 10 free spins. Looking at those issues with appearing / disappearing free spins I wonder what they think about their service? Are they aware that they need to have consistent service to attract people?
