Expecting an answer within four minutes is hardly rational.
I think he was just reacting to what happened to his link once it got posted.
Can't mention the website that is a scraper website.
Nothing personal: you can't mention any website unless it's a Recognized Authority. If you give any full url other than http://www.example.com it will be auto-converted to a clickable link. When you're asking questions about how to word your htaccess, this is not what you want.
Anyway, blocking someone from visiting at all is much easier than blocking them only from scraping. If they work from a predictable IP range, a simple "Deny from..." in your htaccess will shut them out. If they're faking their address, a rewrite using either the User Agent or the Referer -- whichever is appropriate -- can achieve the same thing.
In this case, your Recognized Authority is Apache [httpd.apache.org]. Bookmark the page ;)
