Recently, when I checked my website's backlink profile from Ahref, I found a newly generated backlink from thousands of websites that were just redirecting to my website.

and backlinks type look like... For example,
Like above, around 3K backlinks were generated suddenly.
- Do you have any ideas/experiences about this issue?

Many thanks for your answer and thoughts about this issue.
