Just a warning to those with non-US facing sites that have just been pandalized: We went thru our site deleting everything that we thought might be "thin" content (after we got hit by US Panda). Some of it was quite useful stuff with lots of helpful user comments. We deleted the lot in our desperation to get back into the G results.
Nothing worked or helped - so be careful. AS far as we can tell our site ticks all the boxes for G's quality guidelines. Sadly now it is outranked by all the scrapers.
