I know you’re a Piefed developer, so you probably know what’s possible and what’s not better than me. But honestly, the encryption part makes me think you probably want a new protocol designed with that in mind from the start. In my opinion, it’s too destructive for compatibility with other ActivityPub software and instances running older versions of them especially.
Combating spam despite the simplified account creation will probably require the implementation of something like Reddit’s karma system. Which isn’t a very popular idea I think.
Regarding the ephemeral content… please don’t. It might sound cool on paper, but it just adds FOMO. We shouldn’t promote doomscrolling and brainrot with the addition of features which require you to quickly scroll through shit to not miss out on posts that disappear after a timer has passed.
Considering the sub in question is /r/redditalternatives, you posted this in a thread about alternative communities on lemmy, and there’s a reply to your comment which promotes more lemmy (and mbin) instances that isn’t removed… I really really doubt the reason for the ban was you mentioning Lemmy. That would be very inconsistent of the mods, and actually suggest a vendetta against you personally rather than lemmy.
Did you reply to the message asking what rule you broke? Like the ban message instructs you to? Might have also been an accidential ban.
Sadly, sidebar rules on Old Reddit aren’t real and so can’t be relied upon. There are in fact more than just four rules. There’s nine of them.
That said, even with the expanded list of rules I can’t find any that might apply. Unless their automoderator is so heavily sensitive to non-civility that the very word “cuss” is seen as bad language. Which I very much doubt. It does mention that linking to websites containing malware leads to an immediate permaban, but I doubt that’s the case here?
