Cnet should not have any bots on their site.. I'm pretty sure they don't.. please do not spam Cnet..
Crawlers are not spambots, though spambots usually use some crawler stuff, and spammers can make corrupted crawlers that hunt for e-mails. Crawlers are usually good(its how you get indexed in search engines) unless you want to hide information. If you want to hide from crawlers do a search on " robots.txt ".
It is illegal to spam. Companies do not do it directly, and most of the time they don't want spammers hawking their goods.. the spammers are hard to track down, and quick to start back up again.. its hard for them to shut down spammer accounts for good.
