>>12197246The numbers indicate pixiv, yes, but the additive, "_m," leads me to believe that they were posted somewhere else and the knowledge of where that, "somewhere else," is is the only thing I can think of that would be setting him off. Unless it means something else.
Doesn't pixiv add that to the medium size, that is resized, versions of images? That might be it, too.
>>12197247I don't really care one way or the other where images come from, as long as they're not terrible to look at.
