Hi everyone - we're still hit with the -50 for our main site (we were hit with the first wave mid-May). We do not believe that this is the result of an algorithm change, at least for us. We are convinced, 100%, that we have been penalized. It seems like Google is handing out more -50's lately and is more strict on back link strategies. I wish they would finish these changes already, though. It doesn't seem fair at all for those of you who *aren't* penalized to be losing so much in the serps. Anyway, this penalty is getting to be ridiculous for us. We are very close to 301 redirecting the penalized site into a new one.
