Were the posts done by a spam bot or by registered users?Users ; i removed it after 2 days only . , why google do this for just 2 days .You cannot be penalized for sites/links that point to your site. If you could, competitors would be using this technique all over the place.You also said:"spammers posted a PORN posts ,which increased my traffic to 2x , Once I saw these posts I removed it , my traffic started to decreased rapidly until now it is 90% less"So you are still are still up 10% then before the traffic from the porn posts right? Why don't you see where your traffic dropped off. Are you running Analytics? You should be able to find the source down to the keyword where the drop-off was.Thanks for your reply . my site has a PR7 and large set of keywords that traffic come from , i didn;t make any changes to it .Well if you do a little digging in Analytics you should be able to see what source/medium/keyword the loss in traffic has come from.There are 44,743 keywords80/20 rule apply?First thanks for your reply .What is rule 80/20 . sorry for misunderstanding .
