Best Blackhat Forum

Hi, I need badly an answer.If i use expired article from web archive.

Is that harm for my site or google can kick me ?

Please answer experter.

I can collect article manually or can use lots of expired article collection software That is not a problem.

I have been doing that on "Wayback" for ages and have had no problems with it as long as the article is not used elsewhere. I usually add at least a few paragraph to the article to make it my own.
