NSFW discussion is allowed as there are many Vocaloid songs with controversial or mature themes. However, fanart posts cannot have exposed nipples or Genitalia. Additionally, NSFW posts can be removed at moderator discretion if it interferes with quality discussions on the subreddit.
Act civilly.
Be polite and courteous. Act like an adult. Arguing in the comments is not allowed. Do not respond to somebody acting incivil, report it to the moderators instead. Do not bring in drama from outside communities. Do not use this as a platform for character assassinations.
Only post quality content.
Low quality posts such as single sentence headcanons, image macros, cut and paste content, MS Paint drawings, screenshots/screencaps etc. are not permitted.
Stay on topic
Posts should be related to actual vocal synthesizers. Fanloids are considered off topic, as they are not vocal synthesizers. Project Sekai, BRS, Kagepro, Evilious Chronicles, etc. is not automatically on topic, so make sure you tie things back to actual synthesizers.

When sharing fanart which isn't original content, your post must be a direct link to the source. (e.g. Twitter, Pixiv. etc.)
Share non-OC fan art once per day.

What the written rules don't show

Unpublished minimums. Many communities remove posts from new or low-karma accounts through AutoModerator settings that are not on the rules page, often before a moderator sees them.
Reddit's own filters. Reddit's site-wide spam filters can remove posts from accounts that mostly share links to their own site, in any community.
The community's norms. Many communities see themselves as peers, not an audience: post where you already take part, and make the post worth reading without the link.

Let your AI read the rules before it posts.
