Hi, i have two questions about tagging that i couldn't find the answer to in the wiki:

1: I'm trying to remove a few tags from an image, but the species tag won't delete itself even after multiple tries (general tags could be removed), am i missing something here?

2: I see some images where species tags are added because of ambient wildlife or objects depicting animals. For example an image could have the ant, insect & arthropod tags because of an ant in the background, or because a character has a hair pin that's shaped like an ant. Stuff like that seems too specific to me, and like it would be annoying for people searching with those tags. Should it be removed or is it allowed?

1. its because another tag implies it, or its locked on the post
2. its allowed. dont remove them. add ambient_bird/ambient_insect or whatever fits to the post if its missing, and you will be able to filter it out from search results
