Can you do a favor for me?

Generally whenever I stay in front of computer, I tried to stay on messenger. That brings me both good and bad impression. For example of a bad thing is every now and then some unknown person knocking me. It’s difficult to communicate with everyone always. That’s why I found a filter option…..

Whenever anyone knock me I asked them “Can you do a favor for me ?”. IF they say, yes (If you like to chat with me like friend then should be able to help me like a friend) then request them “Please visit http://shahanaus.blogspot.com and click on any Google ad”. If they agree then I continue chatting or just ignore them.
