IMO if you post something online you should be aware that it could (will) be copied and reposted.
Either by humans or bots made by humans to do just that.
Literally every time someone “views” a picture or video (or anything else you make available online) their device makes a local copy of it, and any proxy servers it passes through may even decide to copy it so it can be cached for later.
Apart from direct OC content most is older content being re-discovered, or new content from a studio.
Not a mod, but it seems fairly obvious that the interpretation of the rule must be that the content was made with consent, and posted online with consent. Not the re-hosting or re-linking in this instance.
And yes, the person in the content may later have a change of heart and contact the mods and say “please don’t keep this post of me up”.
I’ve seen lots of good content disappear this way, but it’s the subjects prerogative. There’s lots of creeps online that will do everything they can to make someone’s life a hell for posting adult content online.
The least we can do is be supportive when the subjects we objectify objects.
If we support people’s right to make adult content we must also support their right to withdraw that content to the extent possible.
