How can I permanently remove my twitter account from google?

[Amberftw]

I created a twitter account ages ago, and I feel like it's come back to haunt me.. I deactivated it ages ago but if I google myself then it keeps coming back up with stupid comments I've made, and i really need to get rid of it! Any ideas? I can't reactivate it and I can't do anything with it, I dunno what I can do :/

Twitter has a high Google search rank, so chances are, your profile will show up in a Google search. Depending on the degree to which this bothers you, you can do several things:

change your real name
change your user name
protect your profile
Keep in mind that words in updates may also be indexed and come up in a search.
Why am I Listed on Google after Deleting or Protecting my Twitter Profile?

All public tweets posted before an account changed to protected will still be indexed in a public search engine, including http://search.twitter.com. No tweets will show up after the time of protection.

Google and other search engines cache search results, which means that occasionally old information is still posted. Although Twitter changes your settings immediately, these changes don't erase old information in Google's search index. Any/all old links appearing in a Google search thus lead to Twitter's truth-telling error page: "That page doesn't exist!" The old links still appear because Google and other search engines may not have the current information updated in their search index. Until Google updates the new information and indexes your current status, links to the profile or updates posted prior to removal/protection remain online.

Send Google a Request to Remove the Information

Google will eventually index updated Twitter information. If you'd like it done sooner, notify them post-haste. If you can click on a link in a Google search, and it takes you to a dead/error page, you can request removal of that link using the URL removal tool. Here's how:

Copy the URL you'd like removed from the site (for example: http://twitter.com/username/statuses/12345678)
Navigate to this page.
Paste in the Twitter link that you'd like removed
Submit your request.

You may be required to log in to your Google account. If you don't have one, you may need to create one.
