As I pointed out a month ago, it is not broken, it is deliberately taken offline every time the price of FUN drops too low.
The reason that the WOF spins have worked this week for a couple of days is because the price of the FUN rose suddenly to 7 Sats for a few hours at a time, which (not) coincidentally caused people like me to get offered their daily WOF spins.
I do believe the WOF are being withheld intentionally and it is not a bug. Your theory about there being a price which triggers a pause in spins being credited is interesting but I think there is more to it. The FUN/BTC price was higher in early September, rounded to 7 sats on the site, and there was no spins credited on those days. In the final days of September they did begin crediting spins again, coinciding with a small increase, but when the price went back down to 6 sats they still continued crediting spins for a few more days.
It's possible but it doesn't make sense. the issue is not the spins when the price is that way, its that people can load up on FUN cheaply. It's the sale of FUN they should cut off not the WOF spins.
There must be a logical explanation behind it. Maybe the profit they make through FUN increasements in price is being used to distribute WoF daily spins to users.
If no profit is made due to FUN remaining too cheap for long periods of time, they simply deactivate the feature. Meanwhile, nothing is told to users in order to not cause panic, mass selling and exodus from the platform.
On the other hand, the profit generated through multiplier game and events bets should be pretty enough to afford every expenses of the website with premium program features, right? After all, WoF rewards are cheap quite often.
