@DashEquals @kaniini @Flashfire42 if someone would save your suggestive photos and you aren't OK with that, you wouldn't continue to send them pictures, would you?
But what's the option for your public posts? Many archival bots ignore the robots.txt and to opt-out every account at every archive would be very time consuming. The easiest option would be to stop posting but that can't be the goal, to take away a platform for expressing oneself from someone just because they want their data to be ephemeral
