Probably, but there’s clearly not a lot of interest at present, and anyone running one such instance would absolutely incur scrutiny nonetheless.
It’d probably be simpler to send the information to a trusted moderator on some specialized community through some dead drop, rather than going through the hassle of making a whole system for throwaway accounts, at that.
I’m not suggesting you host a normal instance, I’m suggesting making a fork that makes the instance logless and allows anonymous burners.
The important thing is to be a black hole for investigating origins of posts, right?
A logless instance that does not keep track of accesses/ips/etc would mean that even in the case of a subpoena there’s nothing to turn over, and the ability to make burners with just an id and a password would ensure nothing is trackable.
You will need to make some adjustments to prevent botting but other than that this takes care of cross referencing, in my book.
Basically the same stuff that companies like mullvad do for their VPN hosting.
Why not simply set up an instance yourself with the features you’d like to see?
Anon identities may not work in the strictest sense but I’m sure something like throwaway accounts made without email addresses or something along those lines would be doable.
Because hindsight is 20/20 and people had preconceptions back then that filled in the gaps, as they do right now.
The gaps are and were actually full of nonsense like “he’s my buddy I’ll give him money” but people expect the process to be a lot more reliable and solid, because they think they’d be more careful with that kind of money, not realising that to some millions are pocket change (and nobody is careful with pocket change) and that others gamble with other people’s money and thus are a lot more cavalier.
