my links are rising by 100-150 per day from the same site, good or bad?

Nothing bad wil happen. But more and more links you get from the same domain, there will eventually be almost no value from the new pages. That does not mean that you will lose value from all links from the domain. Just it will be the same if you get from 1000 or from 10000 pages. (This is my opinion, not saying I am 100% sure.)
