Bricklink updated the site to hide them in the site:
Hmmm, I think if I were developing the site now I would make those comments available
in the "favorites" list page as JavaScript tooltips. Or having the user
click a button to see them one at a time.
Although I can honestly say in my time on this site I don't think I ever
looked at that page, only at the bookmark settings on individual stores.
But for now they are still available in 2 ways, one easier than the other. But
a hassle from now on and in the future if they are fully removed.
Thank you for the tip, I found out the hard way a caveat:
If any change is made to the list like removing a store from it, it blanks out
the comment of all the stores on the same page, as if empty comments had been
submitted for them.
