Starting a couple of days ago, the Recent New Users page is behaving weird. After selecting “Yes” to show descriptions, if you’ve marked a user as spammer or click on “View More”, the page returns to its default view/state (i.e., no descriptions shown) of the first page.
I’m using the latest Firefox browser for Mac on the inaturalist.ca website. The same issue can be reproduced with the latest Chrome browser for Mac.
