And? What matters is if there is pressure - not how relevant the sales are. Simply asking for a comment is not pressure, no matter how irrelevant the appraiser concludes the sales are.
Lenders often know that the sales are not relevant. They certainly know that 99% of the time ROVs will not change the results. I have had plenty of lenders acknowledge that they expect no action as the result of an ROV request. They (the lenders) are just asking for the appraiser to provide them a little customer service so they can do the same. The notion that there is always retaliation, or retaliation in a high percentage of cases, if an ROV does not change the value is just not reality. If that was the case no lender would have any appraisers left on their panel.
Can't have it both ways - appraiser can't yell about how 99% of the time and ROV results in no value change, but at the same time assert the lenders are retaliating over ROVs. It is oxymoronic. If the retaliation was as bad/widespread as some seem to claim/think, there wouldn't be any appraisers left, because 99% of the time the lender would be firing someone.

That is NOT what happens in the real world.
