Yes, but you may be missing the fact that the vast majority of Internet users just click links.
They don't know what a URL is and would not recognise one if they saw it.
Up to a point, that's right; but in Google serps that the spammers obsess about, I've avoided many sad sites on the basis of their spammy title, spammy description or spammy URL. Or, frequently, spammy all three. No point getting in the serps if your site advertises itself as 'one to avoid'!
Many search engine users are naive to spammer tactics; but they know a load of garbage when they see it!
