Hello everybody, i know very well you are also facing this problem. In case of Reciprocal Link Building. this happened lots of time. if you create 50 reciprocal link in a week.and after 1 or 2 month if you will check by http://www.webconfs.com/reciprocal-link-checker.php this tool.you will see that there might be some loss in link. it is not harmful. but at the time of Google PR update it will not good. you predict that you have created most link but it not. most webmaster doing this activity they removed link without any information so i think there is need of some agreement. please give me your reply what will be the best way to overcome this activity.
I think we need to come to terms with the fact that links, in most cases have a use by date. Most things in life are not permanent, perfect or personal..This applies to links too..
Do it with people you trust. On a forum like this, you can judge the person by his profile. On the internet, it is a different ball game because you do not know the person.
