[tor-relays] Reduced exit and not IPv4 exit traffic at all

[yl]

Hello all,
how can I used a reduced exit policy and don't allow any IPv4 exit traffic?

The following line in the top of all the ExitPolicy lines in torrc seems 
not to work.
ExitPolicy reject 0.0.0.0:*

What is the order I needed here, first "reject" and then accept or the 
other way around?

Reduced Exit policy like here:
https://gitlab.torproject.org/legacy/trac/-/wikis/doc/ReducedExitPolicy

Webtropia was a bit unhappy lately when UCEprotect listed the whole /24 
for some reason I still don't understand.

But then I thought, why not disable IPv4 exit traffic, there is so many 
IPv6 resources that a IPv6 only Exit should still be fine.

Thanks
yl
