Unregulated beyond relief. It would seem that the information security and administration staff off the website doesn't really understand and or care about the content that is uploaded onto their website. The lack of 2FA/MFA and filtering algorithms have allowed users to upload illegal content on the sites with multiple burner/alt accounts resulting in bans being useful in the slightest. The amount of REAL child pornography and illegal links/marketing recirculating through the website via such alt accounts has become sickening yet laughable. If you are an artist looking to show off your fanart/skills/art then I would stay well clear of PIXIV for the time being until the owners provide better management of their services.
