The fact that a site returns without any major changes being implemented coud mean one thing --

-- that there are elements in the site which trip a filter when its turned up or down a notch or two.

This doesnt mean tht your site is spammy. google's algo cannot be all-knowing, and it makes mistakes. So up to us to find those factors that get it to penalise your site and remove them. It might look like G is broken - after it is illogical that a normal site can rank at no 1 today and no 300 tomorrow and at 1 again after 30 days. But broken or not, I think its within our control to identify the problem areas which throw G off-track.
