This answer is full of affiliate links. They aren't disclosed by the individual who provided the answer. Further, I was amused to see it cited in the 'Are affiliate links allowed' question here on meta, where it is made clear they are not allowed.
Reading the comments, and especially its revision history, it is clear that the affiliate links have been removed by someone else, and then the affiliate links later restored by the original poster.
This has been going on for quite a while, and among established high-reputation users.
Is this acceptable here?
