All theese sites link to each other - in the bottom of the websites, like this:
Partnersites | xxx.org, xxx.com, xxx.net, xxx.com and so on.
Five of the sites are Brazilian, two another Danish.
I know that Google does not give as much 'power' to sites linking from the same server, BUT, does Google penalise the sites for having links from one to another?
I'm concerned because the sites have nothing to do with each other in any way, and some of them are not even with the same language written.
