Do you really think any other content submission service - Youtube, Flickr, etc - doesn't have a disclaimer like this? That they make themselves liable for what their users submit?

And how is this abusive? Why should they be held liable for what their users do?

From Youtube's ToS:

    To the extent permitted by applicable law, you agree to defend,
    indemnify and hold harmless YouTube, its parent corporation, officers,
    directors, employees and agents, from and against any and all claims,
    damages, obligations, losses, liabilities, costs or debt, and expenses
    (including but not limited to attorney's fees) arising from: (i) your use
    of and access to the Service; (ii) your violation of any term of these
    Terms of Service; (iii) your violation of any third party right, including
    without limitation any copyright, property, or privacy right; or (iv) any
    claim that your Content caused damage to a third party. This defense
    and indemnification obligation will survive these Terms of Service and
    your use of the Service.

YouTube, Flickr, etc. don't provide a bookmarklet for uploading other peoples' content.
