But by doing that you would also hide all the straight ero pics from the search. (muscular women with shotas for example)
The tag is the only efficient way to find this type of images.

muscle + straight_shota

That goes to show you that there may always be a way to find what you seek.

Perhaps someday a thread will be made for what combination of +tags and -tags will lead you to what events taking place in an image. It'd be a good way to reduce confusion causes by tags disappearing if they can just find the alternatives to get there.

Since all of the major tags are taken care of, do we have an updated list of problem tags available?

I haven't gone through every tag on the list on page 1, but it should be mostly up to date anyway.

cleaned out suprise_buttsecks.

Ok that wasn't a very good example from me.

Sorry.

Another example:
What would you do if you want to find straight pics of MFs and adult males without seeing posts where only the dude is muscular and the girl normal figured?
How would you exclude a picture like this
gelbooru.com/index.php?page=post&s=view&id=986067
when you are looking for
gelbooru.com/index.php?page=post&s=view&id=46513 ?

You've found the single inconvenience in getting rid of muscular_female.

But, since conceding without an excuse won't do, you had to get rather specific to do it.

And you knew it all the time.

Or alternatively if you want to find all pictures with muscular female characters of any age, and you don't want to exclude some just because there is a male character somewhere in the picture. That's not as specific.
