That email spin worked ok for me but as I sold all my FUN I don't think I will be seeing all the spins owed.
Probably not. Freebitco team haven't said anything about those missing free spins in the email. They have doubled the WOF spins for the next 12 months for all users. Even, those users will get benefits from this who will buy FUN tokens now and keep them on Freebitco. Which means you aren't going to get the missing WOF as you have sold your tokens.
If freebitco.in is really legit, then why is the FUN TOKEN Telegram full of bots posting automated messages? And why is the "Big Wins" thread on Bitcointalk packed with newly registered users making posts?
Because FUN token team have started a campaign recently. Users are continuously sending messages in their telegram group to get FUN tokens for free. And Freebitco have millions of users. Only a small part of them have an account here. This is why the big wins thread is filled with newbie users.
