I have been searching for this for long and seems like there is no general consensus on this, so I would like to know your opinion on: --> Are unreadable backlinks creating a negative impact on money website serps? --> If they are, is it only tier 1 unreadable links that do this or do tier 2 and tier 3 also negatively impact the money website? --> If having English language backlinks linking to pages in another language can hurt the serps. When I say unreadable I also mean 100% unique. I am not asking for the complete truth here, I know we can't see the algorithm so we can't be 100% certain, but I believe that if there are a lot of people using badly spun content for lower tiers and it is working for them, then it should mean it works.
