While I can understand why someone wouldn't want their stuff reposted elsewhere, it's a bit of a tough one still cause like, there are so many artists that I would never have known about had I not run into their stuff randomly posted online.
I mean heck, scanlated manga is the same way for me really. There are so many manga I own only because I found unofficial translations of them before. It's always funny when I see the "scanlation is piracy" thing cause well, if it wasn't for that piracy publishers wouldn't have gotten nearly as much money from me as they have.
