What if you, through an alt were to buy a new account? you could add the name to your list, buy the account for cheap and then remove the account from your list. Power always bring corruption @Lauda
Simple *fix*: Keep a
transparent list of the users that were either de-listed/un-banned. I'm not sure if Yahoo does that yet. However, the only people that have been delisted so far are those that asked for reviews or have been mistakenly banned (i.e. only in my case as I had no unban option given from Bitmixer until a while ago).
