I got in on reddit super early. Every few weeks I get a message from someone referencing a comment a decade old, now either featured in some youtube video or coming up in their google search. It's unnerving shit and I check my politics there a lot more than I do here. Just as a matter of user safety it's good that our posts disappear after a month or whatever. Maybe it's eventually a few months or a year, but if we ever return to the normal model of forums preserving everything forever it's a big infosec risk.
Hard pass. If you don't want your old posts being dredged up then do some spring cleaning every now and then and delete your old comments that you don't want people to see any more.
I lost count of the number of times I thought of a cool post or insightful comment/discussion I semi-recently saw on this site and UH OH SPAGHETTIOS it's poof gone, lost to the ages (except the frustrating thing is that *I KNOW IT'S STILL IN THE DATABASE but I just can't see it).
I trust the developers/volunteers that work hard to make this site possible nerfed the site for good reason, but I don't know of any other website that I have ever used where this has been necessary. I'm no dev, so who am I to judge, but I gotta be honest it's super frustrating.
