No way! He's too big a part of the show. His mistakes are an important part of his character. Plus he seems to learn from them in the end. As Twilight's sidekick Spike has an important role in the show just like Twilight and her friends.
That's the impression I've gotten during much of my time in the fandom, but a lot of the posters above have a good point about the more restricted/guarded internet usage of the show's target audience.
