Also, there are so-called “borderline” topics. These are topics that can fit into both sections. In this case I am personally guided by point 23 of the forum rules, i.e. I act at my own discretion.
Good, I take this to be the answer to my question. Both topics appear to be the "borderline" topics. In as much as they fit in the Politics and Society board, they can also fit in the off topic board. Also, if I were to be the mod of PS board and I send such posts to off topic board, I am also not wrong because I used my discretion.
