It's pretty easy to verify what speech on Wikipedia is accurate. All information should be verifiable by checking a reliable source. If you find information in Wikipedia where no source is given and you think it may be incorrect, put in a [citation needed] tag. If no one adds a citation, anyone is free to remove the information.
Of course, many people who bitch about Wikipedia and how it doesn't work complain that their edits were undone, often because they added information without a reliable source for verification. You can't please everyone. Either you set a bar to clear to get your edits in and people complain that their edits are undone, or you let everyone add anything and people complain that too much information is inaccurate.
The flaw lies in an API that is specifically designed to help prevent against SQL injection attacks.
