Updated: 02-26-24
This is a modernization of the tag projects sticky, adjusted for readability and improved with shiny new searches. This post is segmented for easier navigation to find the tagging project that's right for you. This list is intended to be a useful starting point and you should manually review each entry before editing, search results can be imprecise sometimes and can introduce layers of ambiguity.
Links to TagMe projects are also included if they're available.
If you have any suggestions of what other searches to add, or want to introduce a TagMe project to help resolve these issues, please comment below!
1. Ratings Tags
The rating system provides viewers with a clear idea of the nature of the content before viewing it. It is essential for making sure e621 remains structured and user-friendly, as incorrectly tagged or rated content could (among other things) negatively affect the user experience.
| Search | TagMe | Description |
|---|---|---|
| anatomically_correct -rating:e | x | anatomically_correct is referred to genitalia, so it shouldn't be rated safe or questionable |
| animal_genitalia -rating:e | x | animal_genitalia is probably used incorrectly here, since the rating isn't explicit |
| bdsm rating:s | x | bdsm should always be at least questionable or explicit |
| bondage rating:s | x | incorrect rating on posts with bondage |
| cum -rating:e | x | incorrect rating on posts showing cum |
| forced* rating:e -rape | x | probably missing "rape" tag |
| gore rating:s | x | incorrect rating on posts with gore |
| penis -rating:e | x | incorrect rating on posts with visible penis |
| sex -rating:e | x | incorrect rating on posts depicting sex |
| sheath -rating:e | x | visible sheath with incorrect rating |
