Thanks for explaining and giving the reason for your apprehension... I think Google has more of the baby-and-bath-water issue from algo changes (and possibly, likely some with infrastructure changes) than they do with hand reviews. I'm really glad you're not just spamming away and pretending to 'be the good guy' which I have seen happen here before and makes me apprehensive myself... I personally have been around going on 6 years now and did a free review of a site for someone who RANTED Google was wrong and wrongly penalized their site and cost them their business, but when I looked at their site and saw the 2px black-on-black, linked, H2 in the footer and the Viag / Adult links on the site's link page I thought G was doing a fairly good job, so I'm always a bit skeptical when people are afraid of someone looking at their site(s), because I keep thinking a hand review of mine would get them white-listed...
I understand your concerns a bit better now, and am glad you have worked on diversification. I actually have a site or two that are only word-of-mouth which keeps me from being SE dependent and presents a number of 'different' challenges, but they're fun at the same time.
I also think it's good for future readers to know the 'why' behind our positions, etc. because it might help them out in the same situation, so thanks for replying and explaining a bit... I'm glad to know your sites can stand a hand review and your bigger concern was for another reason.
Hopefully they're sitting there saying, 'Why isn't this one the first result?' rather than 'How do we get it out of the index?' (LOL) - Have a great day.
