dont worry it will not effect your site in anyway. Why it will effect? I will make an adult site and will put all great Sites links. Will it harm them? no it will not. ofcourse
Can anyone explain me the Google -50 penalty, mean if your site is linked to any bad site then your main keywords get banned or they are thrown off to the -50 urls of google search results
You are right. Or unless yo are liinking to them. Google punishes sites that are linking to spam sites not those that are linking from them.
