Right now I'm pretty new here, I browsed Steem for a few days, and only after those few days I discover 'resteem', then that I cannot do it, then the limit, then got infuriated by its apparent silliness, then I read your explanation and it makes perfect sense.. No millions of points for Doge picture or RainbowCat etc just because they keep popping up from the history.

However, 7 days seem very harsh. Previous 7/30 sounds better to me (I'm a slow writer.. when I write something on my old site, people tend to notice it after a month or two maybe..), but probably there was some important reason why that was changed..

Anyways - many thanks for the explanation. This should be clearly indicated on Steem tutorials!
