is there a username scraper?

i was looking around but couldnt find anything with a few searches. I was wondering if there was a youtube username scraper, so i can gather and save a list of usernames. i want it to basicly be a spider and crawl for user names. Any ideas?


Thanks much

cant edit my post, apparantly i didnt look hard enough. most bots do this, i remember awhile ago it just scraped their id not username. disreguard this post.
