Felipe found an XSS security flaw on my website's landing page. He kindly told which one was affected and I could fix it. I do not run a big company (self employed) and cannot afford huge paypal rewards (at least for now, it hope this will change ;) ). If he finds something wrong on your website and you can reward him, just do it because he truly deserves it! Highly recommended. Thanks a lot man! |
