Remi Gio , I think that there is something lost in translation here between the two of You.
Traffic Hamburg did not mean to attack You, he was just a bit surprised that You took the complicated route of uploading the picture twice (once to the gallery page and once separately to Your post).
As far as I understand this, and also having consulted the rules again, I don´t see anything You have done wrong or contravening what has been written. Neither do I spot any accusation of anything untoward directed at You. Such a communication in a language in essence foreign to both participants does have a slightly elevated probability of misconveying thoughts and causing unintended offense..
So let me suggest that there is no need to retract any entry due to a mere misunderstanding
