Huh, that's an interesting approach. It's still not truly private though

The anonymous profile cannot be associated with its controlling account by anyone other than your PieFed instance admin(s).

So it the same situation as Reddit where the record still exists, and you've just got to trust your admins not to sell you out.

If you're truly worried about it to the level the other comments are suggesting, you're still better off treating them as public anyway.

Really my issue is I just cannot wrap my head around why people are treating votes as more sensitive than comments. That's really backwards imho. I think the only people protected by having votes be so private are the people abusing them
