As I said before, currently I wouldn't allow spinners at all.
At one point if you remember I wanted to bring them back, we did a test with smidsy.

Too much going on with the rebrand, there is an avenue to get them back safely .. But I don't have time to deal with it at the moment.

Maybe in the summer when things quieten down we can explore it.
It would take a couple of people with some very well built machines to start exploring it.
