I'd love to use this service if it was offered without crypto mining and it didn't pay hosts in Ethereum. A community Blender farm could be nice. One that mostly mines coins is not for me.
I've just started using sheepit and I love it. I rendered a project in 15 minutes that took 7 hours on my own hardware. Now I just leave my windows PC running jobs from sheepit to build up my points and in two days I'm already well in the green.
We understand that the crypto payouts aren't for everyone. We started with crypto since many of the hardware owners on our network are crypto miners with multiple graphics cards, but it's on our roadmap to offer payouts in USD in the near future!
