It is disturbing, we have about 500 sites linking in and maybe millions of pages. I've been making sites for nearly 20 years and this is the first time I've encounters any sort of ban and never expected this one on this site.
To be frank it stinks, some of my sites are affilate trash as some people might call it, but this one is not. I've always trod a very carefull line with this one for the following reason;
I have the niggling worry that it's not about the site at all. A month of so before this ban I had a big company warning me about the domain name I had chosen to use. I am prepared to take that fight to court because I know I will win but I also suspect they know that too and haven't come back for more. So perhaps some influance used somewhere ? I would hate to think so.
