Ah yes, because getting your posts deleted = getting banned. Totally.
The asking price is very reasonable considering it's 220 color pages with shipping included, but I don't know reliablie this Kuma fellow is: Twitter bio says they've been around since 2011 but there's only a handful of tweets starting at late 2021, so they probably purged all their tweets at some point. Kinda makes one suspicious.
Yes some where confirmed, his patreon had a keeki tag, also I tried my best to look through all the no face pics I had from him (like %30 of the sets had face) and try to see if an moles matched but I couldn't find any we don't have. I will admit that all I bought was his $40 tier which promised to be everything
Kuma was an anime figure collector before becoming a photographer, he met Keeki on a convention and took photos of her anime cosplay but he developed an interest in lewd anime figures and lewd modeling around that time. lolcows say he was Keeki's boyfriend but I can't find any evidence of that. Keeki took many softcore shotings with Kuma and a couple of cosplay shotings and then disappeared, they only collaborated for about half a year or so. I don't know if they fell apart in good terms.
Keeki posted part of the lingerie she used in her kuma photoshots on twitter, she also liked all the photoshots she appeared in with her social media accounts. She didn't show her face but still gave a nod on what photos are hers.
