I work for a few a cities in Europe, and happen to know one of the cities had a site with an sql injection issue. An external person found and let the city know but didn't want to reveal the specifics before getting money. The city has no bounty program and for some people in the City it came across as if the guy was distorting them. The guy probably felt like he didn't get money for his work. Probably both have a point. In the end it got resolved.
