and I got reported and banned instead, for a month, can you report him for me?
It's natural to get angry at trolls, but keep in mind that you are actually rewarding them if you make the mistake of publicly reacting to their trolling. After all, that's the exact thing trolls are looking for. While high level trolls are more subtle and try to sow discord by careful manipulation of discussions, meaning you might not even realise they are trolling before it's too late, but low level ones, like the one here, are merely trying to piss everyone off and wish for someone to fly off the handle. Of course it's also possible these repeating comment downvoting trolls are connected to the same individual(s) who hacked Mangadex a few years ago, leading to the long year of Mangadex being offline.
So, try to remain cool, like Oogami.
