Altavista killed doorway pages for the first time on Black Monday, October 25, 1999.
Oh the irony that Google is the biggest doorway site in the world!
Altavista clearly didn't do a good enough job!
Also how does this...
URL Hijacking, registering a close and similar misspelled version of a successful and profitable brand, company or competitor
..have anything to do with SEO?
If I type a URL in my browser's address bar I go to the website, no SE was involved in the transaction. Yes it's unscupulous, just spell Goolge wrong and see where you end up. But this has absolutely nothing to do with SE's or SEO.
Or are you seriously saying that two companies with similar names and web addresses are penalised for this fact and one will be given priority over the other and the lesser one is penalised?
This would be so totally and utterly outrageously wrong if it was so!
Perhaps you are confusing this with real URL hijacking where a website is compromised and a piece of code is injected into the website to redirect the user to another website or as the NSA implement it utilising a 'race condition', to redirect you to their server instead of the real one and display fake content so they can start attacking your computer with viruses and other exploits.
The fact someone can't spell or has made a typo and accidently come to my site instead of someone else's doesn't mean I have just hijacked their URL.
