The big scary red warning page should at least tell you it’s phishing or malware or something else. OP didn’t have a screenshot of that. You can easily go to a safe browsing test site yourself at testsafebrowsing.appspot.com and find that Google does divulge the category of the blacklisting.

OP says:

> no gore or violence or anything of that sort

That’s not even the right criteria. OP is confused about Google Safe Browsing vs Safe Search.
