As far as I know, there's one registered user whose admitted to using POCALOID but they've never published anything with the software and are inactive here; not blocked. There's also another very infamous user/ producer here who's inactive and not blocked. I don't think they're coming back anytime soon (or already did to the community under a new alias).

So long story short, using POCALOID doesn't get you banned, but you do get looked down upon for using it. As far as I know, there aren't any active users who use POCALOID.
