Believe it or not, that GIGANTIC, absolutely un-missable disclaimer was not there yesterday… or at least it did not show for me for whatever reason, definitely on mobile Firefox and I thought I had also looked on desktop but now could not swear to it. I cannot offer definitive proof but here’s a snapshot from Sept. 28 - not quite yesterday but long after July 1 https://web.archive.org/web/20230928153646/https://subredditstats.com/r/askreddit but still is missing that disclaimer. In any case, thank you for the note of caution: possibly results might be comparable across subs but perhaps not pre- vs. post-API changes.
