I wouldn't give up that easily Federico. Let them know they've made a mistake and try to go through the appropriate channels to handle this. That's what I would do. You clearly have a little following here already, and it'd be a shame if you left just because some stupid bot and its over-zealous algorithm flagged your posts. I still look at your posts everyday, and I also find your content to be well balanced and informative.
