I bought backlinks from a provider on WF, but those backlinks might be a black hat technique. The backlinks are coming from forum comments.
This provider did not provide proper work, such as the backlinks are missing, and a keyword is wrong. He told me that "I will resend you report."
Today I got the report again.
When I checked them out,
1) 2 backlinks in same keywords are coming from same Forum websites.
2) The comments are same.
For example, he commented 2days ago for a backlink.
And the comment and backlink are xxxxxABC. myurl.com
Today, I got same comment and backlink: xxxxxABC. myurl.com
I heard that this technique can have more chances to get G penalty.
Is this black hat SEO technique?
