What are you doing that has you worried about strangers filming you? I'd be pretty offended and creeped out if a total stranger was following me around filming for no apparent reason but that isn't something that happens presumably because I'm not particularly interesting. I opened this comment section because I was perplexed by the premise of the title and after scrolling a bit I remain entirely unable to comprehend the underlying motivations.
