MOZ fake DA increasing in some websites

Hey guys,

couple of month ago I saw some anomaly in DA, so I just wanted to share with you.

First of all you can see your DA back to one year in this website below:

So, if DA increased in one month more than 50, I mean for example DA 10 to 60 it is absolutely fake!

you can see DA for these to get the idea.

isna[dot]ir : correct DA

foorofan[dot]com : Fake DA

gostaresh[dot]news : Fake DA

So, if you had any questions just ask me!
