Recovery from Bing deindex

I just want to share some tips about the way to recovery from bing deindex, my site got deindex the in early this month, at the beginning, I thought it's a "mistake" from bing as the site is ranking fine in bing for 5 years, so I contacted the support team from bing via email, and they replied me that the website is in their "block list" due to violence of guideline...
And the next manual review will take place in the next 2-3 months.

I decided not to wait for such long time, so I disallow ALL of backlinks from Bing webmaster tool, after 1 week, my website is back to index and rank in bing again...
I do have a bunch of PBNs toward my main site, and I have 3 * 301 redirects to my main site as well, so I believe the deindexation was caused by the backlinks.
This means Bing has successfully detected my PBNs and penalize my site for it, if that's the case, I strongly believe Google is able to detect the PBNs as well, but choose to devalue or ignore those backlinks, and this explains why my site doesn't rank well on Google no matter how power the PBNs are.

Anyone has similar experience on this?

Let me try this . will let you know the result

You should have tested first with the 301s and then the PBNs to be sure.
