A user on Reddit pointed out that Richard "rick752" Petnel, maintainer of one of the most popular filter lists for Ad Block Plus, has passed away at age 56. In an article last year Petnel described a bit of what he was up against in the ad world. "'I'm playing against some pretty big players,' he said, explaining his reluctance to step forward. 'I don't want to be harassed. . . . I don't want to be bribed. I started it because I was frustrated with getting my computer infected from ads -- malware and spyware and all that stuff,' he said. 'I kind of went overboard with it. But you have to admit, it's pretty amazing, right?'" Update 15:05 GMT by SM: updated to reflect Rick's status as maintainer of the most popular Ad Block Plus filter as opposed to Ad Block Plus itself.
