There was nothing in any of those articles about Luigi Wewege committing fraud. Engaging in slimy politics? Yes. Knowing other people who may have committed some type of fraud? Yes. Fraud committed by him? No.
The title of one article sums it up best: "The colourful life and times of Luigi Wewege" Living a colorful life does not constitute fraud.
People should be careful about spreading false innuendo.
