The report system apparently goes only off the number of reports, and who sent them (ie, 1 player can't spam a bunch of .reports, afaik), and records no audio. The voice report command, .vreport or reportv, whatever, is basically useless. If you want a response, you should just send HTC the film. Without film, you won't get anything. I don't think they even look at the reports unless there's an issue they're aware of.
