I found a plugin containing the following code:
<div style="display:none;"><a href="http://www.24wn.com">news and information</a><a href="http://www.forum1000.com">business,health,entertainment,technology</a> <a href="http://news365online.com">automotive,business,crime,health,life,politics,science,technology,travel</a></div><div style="clear:both;"></div>';
I don't think this is legal. It can lead to google site penalization. How can I say to WordPress?
