Update: the stolen content is now removed from the offending site.
I was notified that a seo24.at web site republished my article about TYPO3 performance optimization as their own thus violating my copyright. Here is their copy and here is the original. Pity to see that there are still people like this one. The could have asked and got permission immediately. Now I have to ban them from republishing anything from this site... I like to share and promote the knowledge but I hate content stealing in any form.
