Hi,Just a little confused by the question - you mention the fact that there are "no manual webspam actions found", but also say that your site has been under a penalty and released again.

Do you mean that you have had manual actions in the past that were resolved, or are you simply meaning that you have seen three different traffic drops which you refer to as a "penalty"

OK, so if there is "no manual spam action" in place, then you are dealing with either an algorithmic issue (which would include the affects of having any of the recently devalued link networks included in your backlink profile), or a direct technical SEO problem.

First and easiest to identify is an unintentional Technical SEO SNAFU:

1. Have you changed anything recently that might coincide with the time when you see that drop in traffic?
2. are there any issues highlighted in your Google or Bing Webmaster Tools accounts (crawl issues, changes in blocked or no-indexed URLs etc)?

When it comes to figuring out whether you have been affected by recently devalued link networks or other algorithmic issues , I left some ideas in a comment here http://moz.com/community/users/211679 earlier today which might be helpful. There are also some tools available which help to see if changes can be tied to algorithmic updates like the Panguin tool.

Hope that will give you a start on identifying the issue(s) and then you will be able to see your way clear to fixing them.

The patterns that you are describing make me wonder if the Panda algorithm is affecting your site.  Panda is about on page quality as opposed to the backlinks pointing to your site.  There was no Penguin refresh that I am aware of around the dates that you mentioned, but as Google doesn't tell us the dates of Panda refreshes, this is certainly possible.

Two of the biggest culprits for Panda are having a large number of pages with very little content (i.e. thin pages) and having duplicate content on your site.  According to Google site search there are about 210,000 pages of your site in the Google index.  Are these all pages that need to be indexed?  If a large number of these pages never receive traffic then this could be a measure of low quality in the eyes of Panda.

If this is the case, then the fix would be either removing a large number of pages or adding a noindex tag so that they are no longer included in the index.

I can't say for certain if this is the cause though, but it's where I would start.  Panda refreshes approximately once a month, so if you clean things up you could see an improvement by the end of April.
