Ok, that makes me curious, why 👎 ? This seems like a very interesting challenge, and also very educative. Is there anything wrong with it? Or anything wrong with posting it here? I honestly do not understand.

My guess: nothing to do with the content, but because this post was a quick follow-up after yesterday's spam post (selling some course) by the same account (and this one also feels a bit spammy, don't know exactly why). Content itself looks interesting and relevant for this channel.
