Totally understandable.

That said, on subreddits I see people who post content without attribution all the time. I recall in /r/aww you can't directly link to an Instagram post but you can "steal" the image and post it, and it's optional as to whether or not you link to the Instagram post within the comments. Likewise, people take videos from YouTube/TikTok and re-host it on Reddit.

In smaller subreddits people will post entire pay-walled articles as if writers only get paid in likes.
