I really thought all would be alright before the end of september but now we're almost at the end of october and WOF spins are not daily credited, and days to upgrade to the next premium membership level are not counted.
So far there was no signs that they're going to fix this issue. When they enabled Premium WoF spins few times it was more like false hope.
If any other service would have similar issue, I guess that most users would stop using them. Freebitco.in still have trust credit from their users after so many years in business, despite that issue is ongoing for few months already. I still hold quite significant amount of BTC there too and I'm actually not sure that's good decision and I don't know why I still didn't withdraw my funds.
Yes, they are having problems for whatever reasons and they may eventually quit if they are unable to get these issues fixed. But i will not call this act of them as exit scam. It would be much better if they can announce they are unable to continue and let people withdraw money.
You never know what will happen next. It's quite often thing when everything starts from small issues and then eventually grows up into huge problems. I wouldn't deny possibility of exit scam.
