Hi I understand that Google may penalise a site if you reciprocal link to spammy sites etc but will Google penalise if it's a one way link from a spammy site. For example: A directory owner adds a reciprocal listing type to his/her directory. Visitors come a long and submit a reciprocal listing. The directory owner rejects the listing because the visitor has linked from a spammy site, but the link placed on the spammy site remains and is not removed. The directory owner has no control over links from other sites. Will Google penalise the directory?
