In your article, you write that a social platform without trolls is impossible. You simply encountered a dumb-ass troll who didn't like the fact that you like Twitter and he reacted this way.
If you look now, your submission isn't flagged anymore, people with enough points to flag can also 'vouch' and counter a flag, so it looks like enough people vouched to unplug your submission :) Sometimes it turns into a tug of war.
