For the most part, I don’t think Lemmy cares what other sites people visit, including Reddit.

That said, mostly site/user watermarks are pretty stupid. Like do they expect some kind of credit for attribution for a meme? And it’s also kind of curious, as I’ve never seen this style of reddit watermark before. What does it even mean? Is it from a cowboy sub?

Crediting the author is not bad idea. With that sticker someone who liked this very much and wants to see more similar stuff may try to track down the source.
