I know of another creator doing the same thing for Fanbox.
https://kemono.su/fanbox/user/57786118They're either monitoring Kemono to update upon import or just updating daily anyways. I've seen posts get imported on the same day and the password already stops working.
Right now their page is getting filled with a bunch of download link posts that are hidden or deleted. Anyone casually glancing at their Kemono page might not know how to find the actual links. Meanwhile they reuse an old post which has to be regularly flagged to reimport.
I wonder if it also slows down the importer in any way having to keep checking for flagged posts that are no longer there.
