You shouldn't be seeing posts with just an image link but clients overload the text note event too much. I hope this changes in the future but as of now I only see Vitor wanting to improve this situation.
so voyage filter out those? well now that I am thinking I don't remember seeing any post that was just one image link, generally they have some words too, but it's not enough context
If it doesn't give enough context and there are like upvotes on the post I usually don't click the link.
upvotes are a bad sign? haha :)
