I definitely don't trust those when they show up in search results, and even when they sometimes appear here in articles voted to the front page, I tend to ignore them.
Sure, if they didn't exist people would use phishing domains like "fedex-secure-delivery-approval.com" or something, I suppose
Many-legit-sounding-hyphenated-words-domain is actually another red flag for me, as that was indeed what they did before the proliferation of TLDs.
