TBF Flatus catching up with a cyclist is != punishment.
IIUC Flauts is annoyed at people passing him without saying "hi". Personally I rarely say much when overtaking, because, to me, breezing past someone and then making point of the fact that I've gone past them is a bit ...
Similar to using a bell on a shared use path, you get grief for doing it and you get grief for not doing it.
If the worst thing to happen to me on a ride is someone making a point of catching up with me, no big deal. I provided you with some motivation to pedal faster, you're welcome.
If the worst thing that happens o Flatus today is that someone call's him a bit of a dick for his behaviour, business as usual on YACF?
