How do I protect of detected unnatural links
 

Hello,

I received a message from Google about artificial or detected unnatural links.

I didn't know why my site violated this policy from Google.

My question is, How do I protect of artificial or detected unnatural links?

I used to advertise my url to a forum, is that the cause?

Thanks.

i think that you should to check your backlinks of your website ,this kind of issue normally due to spamming link.
