It's much closer to reddit than 4chan, otherwise the nature of the images posted would be a little different.

And it's been like this for 2 or 3 years now. I've seen comment spam of images for commits and issues for quite a while.

The first I remember was https://github.com/MrMEEE/bumblebee-Old-and-abbandoned/commi... , but I guess that was a couple of months later.
