Going through the pics of Dracojeff I noticed that someone (https://e621.net/users/1382151) has recently removed almost all trans_(lore) tags and added male_(lore) or female_(lore) to a lot of posts.
There was this discussion in the forum post 'Rivet and Trans Tagging', but I didn't follow it for very long. Did the meaning of male_(lore)/female_(lore) change, because of that or did the user misinterpret the tags?
As fas I remember male_(lore) for example meant 'You know/the artist says the characters is male, but you can't really tell (because of a simplified art-style, they just look ambigious, etc.)' while trans_man_(lore) meant 'Character identifies as male'.
