yo this isn’t the government.
You seem to be wanting a platform on which to conduct official, auditable conversations which are subject to accountability in the form of total mutual surveillance. For some reason pinning these hopes to a random project with a sewer rat for a mascot.
The internet has been going on for like 50 years now, people have been pulling all manner of flame war shenanigans and this has like never been a significant problem. Because if a conversation is being watched by a lot of people, there are always others who saw the original post who can corroborate the change. And if it isn’t, who the fuck cares? Like I said to OP, if you are getting into a lot of petty flame wars and feel you need this sort of thing, learn to take a screen shot or use some of the other many client side or 3rd party tools available just for this kind of suspicion. For the most part it is some kind of online urban legend tho. Plenty of people are saying all kinds of stupid bullshit online, no need for others to plot and plan to trick them into doing so. Whoever is looking to find stupid bullshit can find it without resorting to trickery, in any variety they choose.
I have been on lots of old forums too. That is irrelevant to this thread. This thread is about the ability to investigate the typos on the old forum posts. How often are you on some phpBB site thinking “this would be so much better if I could see what incorrect information was edited out in 2009.”? Nobody fucking cares.
