I would rather not check out those tools mahesh2k but have run across similar stuff over the years. They just change name. I think the point with my PC-Tool hate is that directly or indirectly screwing up search results is more accepted than what I think Renegade refer to in first post. Everyone wants to be at the top. I can understand Googles trouble with how to draw the line. They should fear "Google is useless" campaigns but also "Google is censoring the internet".

Here is a long thread about the question of what is what, what should be penalized or not http://www.google.com/support/forum/p/Webmasters/thread?tid=6dcd2428eb4fc691&hl=en&start=120 He starts off somewhat convincingly but goes downhill fast though he also have a good point by saying similar sites do not have same problems. People disagree of both his site and claims of being penalized unfairly, personally I would not trust him for a second and went YES when a person noted that 1 posters somehow seem to enjoy his site and support his case ;) How old and naive! And after all that chitchat a Google Employee make the last post saying almost nothing other than stating the obvious. I don't think they know what to do with questions like how much original content is enough to cover up affiliate links, what is original btw!

I was more interested in checking how Google handle complaints by suggesting to report a site, preferably one that cannot be debated. How long does it take to get a reply?, is it worth anything?

It is portable, check bottom of site. You have to install full package first though. One of those programs you instantly know can do much damage so no need to warn against it ;) I have had actual use for it a couple of times when a service seem to be stuck in registry.

One way to find out would be to report a site which without a doubt piss all over their own rules and tons of advices on good behavior. Start the clock and see what happens. Do they let a bot give link to bing.com or will you get a human response with argumentation for why and why not.
