From a social responsibility perspective I agree 100%, but I'm also curious as to how the platform itself treats re-posts. Is there anything in the algorythms which penalizes them? Thanks for your reply :)

There is absolutely nothing in the algorithm about it. You will probably have @cheetah automatically commenting but that's no big deal

Ok, that's good to know, thanks. What would you consider a reasonable time before re-posting? 1 week?

4 weeks simply because that's how long the reward for the first is still gathering. You'd be better off bumping the original before then.
