It's about this post: https://serverfault.com/a/573357/468941
I edited it a while ago, adding source material, including a quote. My edit got approved but in the meantime the original author edited the post and removed the hyperlink to the source but left the quote.
I feel that it is unfair to quote something and neither marking it as a quote nor linking to the original content. I do not have enough reputation to comment yet, otherwise that's what I would have done.
EDIT: I just noticed that the original author actually did modify the quote a bit. I guess it doesn't qualify as quote anymore in this case. Nonetheless, my question remains: What should be done if a case like this occured?
