i wondered whether it was the number of the links that did it, or perhaps the kind of links that you got - i would expect a search engine to be a bit 'suspicious' if say those were links all coming from pages or sites with high page rank, or if the links were easily identified as 'paid links'.
that number of links in a month i don't think would be a problem with a more established or authoritative website. but i could be wrong. all depends on the kind of links, i would think.
