Support for SC gets your service automatic distrust in my book.. but hey, for some people, supporting any and every alt currency isn't seen as a bad thing.
I got that you don't like SC, but putting services that support SC into a blacklist is infantilism. You won't win your war against SC this way... But who cares?
Don't be so paranoid. Nobody mentioned any blacklist.
I gave you a perfectly polite heads-up. It's my opinion that some people happen to view SC support as a useful indicator of poor judgement. I know I'm not alone in this. No skin off my back if you don't care about that.
