Google's January Core Update 2020, is this update flushing out sites who buys link's?

[ani2002]

What do you guys think about it?

Because the fluctuations which we are seeing since Google announced to roll out this update seems to be more and more voting on this fact that Google is flushing out sites which were buying links somehow.

A couple of sites in the entertainment niche I knew bought a couple links a year back or so. These sites weren't effected much due to any of the previous updates. Because these sites have a definite viewers base which remains undisturbed (more or less)even if SERP fluctuates. These definite amount of traffic are basically those kw's which no matter how SERP fluctuates remains unaltered.

But since this update those kw's positions as it seems to have changed. Even the admins are complaining that there is a considerable decrease in dialy bot activity on those sites as well.
