SeoQuake SEO toolbar a must for SEO professionals

[glenbolton85]

The SeoQuake is an indispensable tool that can help you estimate just how effective and competitive your SEO efforts have become. You can use the tool to analyze your internet marketing campaigns and projects. You can use it for PageRank, to determine incoming links, DMOZ listing and Delicious mentions. You can also use it to find out if your pages are getting bookmarked and if they are getting into the Whois listings. SeoQuake can also help you identify secondary key phrases according to your existing content. It tells you how often you have used the phrase on the page and how it is positioned in the content (i.e. Title, keyword tag or description)

I personally do not use it, but have read some good and some bad reviews regarding this tool. I have read that is contravening the publishers rights, invading privacy, and you can get banned from search engines if you use this tool too much. Are these statements even partially true?
