Well your not the only one who had this experience
I too fell victum of similar banning and even though Support was able to correct things in the end the reasoning for said banning did not add up in my books as I witnessed posts in the following weeks doing exactly what I was accused of without action
But at the end of the day these forums and game do belong to Palarium and they can run things how they see fit
So I just roll with the punches and try to duck and dodge more than take it on the chin LOL (so to speak)
I love this game and posting my opinions on the forums since I do not use facebook or Discord its really my only avenue
My only advice is to allow support to look into it and let them do their job to lift the ban. But going at it with the attitude you already display will surely get you undesirable results :/
