Is copied continent with permission for Google AdSense is illegal?
I’m Building automotive website that contain car reviews and news, and because of all information about cars is statics so about 70% – 80% of my website is copied articles but i have permission from the sites that i copied articles from, so it’s okay about copyrights but are there any problem with Google AdSense, will that affect my profit from adsense, will google consider my site MFA (made for adsense), or is it illegal for Google AdSense policy?

It is not inherently illegal with Adsense
But Adsense honors DMCA complaints and abuse reports. If the site where you copied your content file a DMCA complaint with Adsense, then Adsense can terminate you from the program

If the sites will not complain, then there’s really no problem. But if Adsense starts trimming down on MFA sites again, and see that your site hardly has anything original and merely copied from elsewhere, don’t be surprised to get the first ax
