onclick is a valid xhtml/html event handler and is often used legitimately. For example, if you don't want to lose visitors from your site you can open a link in a new window. Whilst no-one "really" knows the search engine algorithms, I would suggest the most abused attribute is the alt attribute where some scheming would be webmasters enter 33 lines of text in an effort to "fool" the search engines. Who do they think they're kidding? Web SEO software can pick it up and even if there isn't sufficient contrast between the text colour and the page background colour even if this is all coded in an external style sheet.
