What Reddit "policy" are you talking about? I see you are still working on your English from your past submissions, so I don't mean to be rude, but I don't understand what policy you're referring to. If you're leaving Reddit because of, say, a policy against behavior that is also not wanted on Hubski, then Hubski is a bad alternative. But if you mean Reddit's overall failure to manage their community in a way that would retain more than just the lowest common denominator, then yes, Hubski is an alternative.
Adding link to reddit is problematic. for example, base on their policy, adding two or more pages of the same site is banned automatically. Or even when we observe subredditors policy, most of the times, they reject the link or they completely don't come back to review the subreddit they already created.
