Can we start using a tag called "MMONOOB" or something less direct to indicate that a post is asking "HOW DO I WRITE MY UBER SWEET MMO, NO I HAVEN'T DONE ANY WORK YET, HELP ME?". Then I could just add those to the ignore list and be happy.
This tag should not exist because it is primarily identifying a poor kind of question that is undesirable. If it is undesirable, the proper course of action would be to vote-to-close the question under an appropriate reason. Without the ability to vote to close, one can flag them for attention, or just not visit the question altogether.
Fact is, though, such a tag is not intuitive to new users (who will be the ones who keep asking such questions). This means that such users are not likely to ever add that tag on their own, so you would still see those questions. Existing users who visit such a question, again, should be voting to close or otherwise dealing with the question, not adding the tag and being on their merry way.
The fundamental problem with such a request is that you're asking for a meta tag. Meta tags are explicitly discouraged: http://blog.stackoverflow.com/2010/08/the-death-of-meta-tags/
mmonoob wouldn't describe the content of the question other than being a meta tag for "beginner" mmo questions. Which would be the same thing as tagging a question as beginner and mmo. And since the beginner tag is destroyed on sight, you can see where I'm going with this.
