I'd hope not. Those at greatest risk are those that have done nothing with bad link profiles. There also appear to be some false positives which could be occurring in either direction, so I'd keep a careful eye on anything that could be further culled, while replacing them with good links, where and if you can. It's a balancing act - keeping ahead of the threshold, whilst Google reserves it's right to dial things up.
