If any very-veteran members want to volunteer, I can give you the ability to whitelist users.
I'm interested in this one as well...
Before whitelisting someone, you have to do something to be pretty sure that they're not evading a ban and just going to get banned again.
If volunteers are limited in the exact same way that we are when it comes to connecting the dots for alt accounts, then I think the current staff would probably do a much better
[more accurate] job
[assuming they have additional resources at their disposal].
