unfortunately it seems that people are trusting google search results to be accurate without following links.

as far as I can tell this is a combination of reddit returning the subreddit creation date as the timestamp that will show up in search results yet including images of recent posts, which google will then use as an indicator of “the image exists on this page”. this will lead to a 7 year old subreddit with recent posts showing as the image being present on a 7 year old search result. if people actually follow the link they’ll see it’s just a link to the subreddit and not to an individual post.
