Then I'm probably misunderstanding how the implication system works. From how I understood it when a tag is implied by another one, the implied tag gets automatically added to the post. When a tag is newly implied, then all posts on the Booru who have the tag that implied something but not the tag that is being implied will be updated automatically.
For example, "thighhighs" might imply "socks" or something, so when I add thighhighs then automatically socks would be added to the tags. For the case that this implication wouldn't exist when the tag "thighhighs" is added but the implication to give "socks" is later created, then (I thought) the system would automatically add the tag by itself.
If this assumption is wrong, then the implications above wouldn't update anything, thus not increasing the amount of posts who have those things but lack the tags (thus the numbers are wrongly low which in turn makes people not bother with them).
Also, the search limit is 2 tags. If I search for a specific character with a very specific type of clothing and I would have to choose which tag to use because the very specific tag doesn't exist (only by usage of 2 different tags), then it defeats the point.
TL;DR if misconception from my part please ignore topic.
