The shipping is mostly a fan thing since they're so close (and also fujos so they love shipping too) and they don't even feed into it from their side.
As far as I know, though, Pomu mentioned having an ex girlfriend which ended badly, and Selen once mentioned an ex-boyfriend like 10 years ago or some shit, and knowing her, it was probably puppy love with another online artist. (This also ended poorly, allegedly)
Nowadays though, Mint seems more into yuri (sex) than yuri (love), and Doki'd rather shlick to yaoi, robots, or robot yaoi.
