These are sites about news, nothing to sell, and LOTS of pages :(
I would start not by looking at only the sites, but by looking at the business model.
How unique is your site? Are there lots of others (in Spanish) ? Are other sites doing entertainment news in Spanish still seem to be holding up well in Google, or did they see drops too? Are your news items pretty much the same ones that other sites have, or do you have some stories/posts/content that are rich (not shallow) and exclusive to you? Has traffic to all parts of your site dropped equally, or did some sections suffer worse than others? Do you post the full content on your site, or are you an aggregator (a la the Huffington Post, for example) where you post excerpts and then links to the complete story?
This is where I would *start* looking, if I thought I had been pandalized.
