I've not really seen much indication that they're abusing the system. The one commenter above claims the app sent the same letter twice, someone who works for Fixed said that they don't send the same form letter every time and both tickets must have had the same error (which would generate the same letter). In light of that, I don't see why a form letter specific to what makes the ticket invalid is an issue. Why should someone have to come up with a hundred different way to say "There isn't a 'No Parking' sign within X feet, as per city ordinance YYYY". I also just want to point out, the SFMTA has brought this on themselves. If they didn't have such an egregious erroneous ticket rate, Fixed could never be profitable. They only get paid if you don't have to pay the ticket, so if the SFMTA had an error rate of 5% rather than 33% Fixed wouldn't have enough to work with.
