Just keep it in perspective... the dude flagged you for a cent, and just because a small group of volunteering vigilantes agrees with him, that really doesn't mean much in the grander scheme of things.

I am supporting SFR very much and I do believe the group plays an important role in raising awareness for proper steem-etiquette and a small role in protecting the reward pool from actual abuse...

BUT, I also see how overzealous and poorly communicated flags can throw a gut-punch to genuine engaging users on the platform.

No system is without flaws, I hope you'll get to spark a fat one after all this noise and let it sink. I'm sure there's plenty of good for you to do and plenty of support that you can find for your goals here.
