Keep going with my Kelsey internet wide search, I found 2 "interesting" links.
https://detail.chiebukuro.yahoo.co.jp/qa/question_detail/q11166743161
This first one was someone asking on Yahoo Answers JP, what's Kelsey is doing and someone replied that he was taken care by her on Pink Salon in Shibuya recently.
For those who doesn't know,
Pink Salons are a place for quick and cheap sex on Japan. I personally would take the comment with a big grain of salt because I couldn't find anything extra, the guy doesn't give any extra details like if she's was a sex-worker, clerk or anything or if he's certain that it was really her. I personally think the guy mistook her but I don't put my trust in her too.
The second one is this one:
https://www.tekoki-fuzoku-joho.com/column/m500540/
This one she talks a lot about her sex life, I unfortunately rely only on machine translation as I don't know moon runes, but you could infer that she has done sex for money on Japan and Canada but the machine translated version is very ambiguous, so feel free to correct me.
I tried to archive both websites but archive.is keeps failing
edit: Forgot to put a screenshot/translation of the yahoo answers post
