Will there ever be an option to EXCLUDE certain tags?

for example...the Japanese REALLY tend to throw either Harem or Incest in my favorite genre of reading, Fantasy.

So no matter when I search for Fantasy, this, or that, or all of the tags I don't like are in it.

Some of these things I've been reading since I was a kid and I have since grown. some of the things I used to enjoy are now kinda creepy...

Type in "-Incest" in the Categories/Tags Box and exclude the harem genre while using the search function.

I also read EU/US comics and am a librarian.
Manga-Masters, My ANN-Lists + Imdb

Go to Genre Search

Check to red box to exclude genres like Harem.

Below that is a box where you type in categories, just add a "-" on the categories to exclude it.

Thank you, finally found what those red boxes meant... really appreciate it!
