Articles removed

Hi,

I have earlier posted my articles on some article submission sites including Articledashboard and all my articles were approved and published within a couple of days and there were around 8 articles were published at Articledashboard but last week when I go check my article status at Articledashboard I was shocked there were only two articles and rest of 6 articles were removed and not showing in my article stats and URL of my articles where these were published were giving an error when i go to visit them......I am confused about it what is this why may articles were removed after approving and publishing? can anyone suggest me what's all this?

thanks

How many different sites did you post the same articles on ?
How many other sites have other people posted the same articles on ?
