According the F95 official stance, The Dev notes don't count as tags and Tags are only supposed to be used for content already present (Planned content goes in the Dev Notes, not Tags). And yeah the Rape tag is less than useless to anyone except snowflakes desperate to avoid the barest hint of the kink, similar for Gay & NTR.
[Tags are the clickable links at the top of the page, below the title, next to the Devs name and start date]
Based on some conversations I've had with a few of Devs, they have limited control over the Tags on their threads, a couple have struggled to get Tags Added/Removed having to file tickets with staff rather than just edit them themselves. (not sure if this is everywhere, some seem to have editing powers (or used too), while others don't ... I have no idea why)
Edit: WE should really end this conversation though, it's going off topic.
