I hate to report it but after experiencing great results with link joos initially, my site was hit by the penguin 1.1 update last night. I don't want to say that this service caused the problem because I don't have any way of knowing that for sure but this was the last service that I used for this particular site. It is possible that this is nothing to do with link joos and was down to something that I did months ago that all of a sudden penguin has decided it doesn't like but I wondered whether anybody else had been hit after using link joos. Sorry Tom, I am not trying to derail your thread, just trying to get feedback.
