How do I add the Game tag to my blocked list?

Let me preface by saying I don't use this site for games, just reading manga & doujins. Which is why it's extremely annoying whenever I get a notification for a tag I'm following and then it's another game. The search function will let me add any tag to my blocked list, EXCEPT "Game"? Am I missing something or is this just bad design?

It doesn't matter, blocking tags hasn't done anything since the site downgrade a year ago
