Hi guys Iím a bit confused on this. First of all I would like to know that are sites penalized or does it have any ill effects on a particular site if the backlinks are from a low PR site?? There are many who say it does. So if it happens this way it could have some big implications for things like forum sigís, which automatically appear on lots and lots of low PR pages. Or maybe they can tell which ones are sigís and which aren't (may be its possible). I can also see why this would be a problem, because spammy links would appear on a large number of low PR pages.
Your comments are appreciated and thanks in advance.
