 few days after the XSS was fixed but i was having no response.. at leaast no mail saying "Thank You". i really find myself very frustrated when the companies like these doesn't even thank for finding a security bug. but after few days i have find a reply from the guy itself to thank me and leave a lame excuse for not replying me.
