I generally hate it when anything is unsourced or not linked to the original poster. This includes photos, writing, articles, videos, etc. But nothing ticks me off more than unsourced art. Like, it’s not hard to link to the original source when you post - there must have been somewhere where you saved it off of, and if the place you got it from didn’t source and it isn’t theirs, then enter that image into images.google.com and find the source yourself. It takes less than five minutes, usually.
AND IF IT COMES FROM TUMBLR, THEN JUST REBLOG IT AND SAVE YOURSELF FROM LOOKING LIKE A TWAT.
It’s not enough to just link to the artist, either. Link to the actual art. if you’re going to repost something, then take the time to be a decent person.
Taking screenshots of something and posting it unlinked is just as bad.
If you made it this far, then here’s part two:
ASK PERMISSION BEFORE REPOSTING OR POSTING EDITS AND LINK IT TO THE ARTIST. Use google translate for any speakers who don’t speak your language. There are reposts of art that have more notes than the art itself, and the artist doesn’t even know about it. And if the artist doesn’t give permission, an idea is to just link to the original source without posting the image, and giving a brief description of the picture along with the warning that the artist does not want it to be reposted.
(But, if you’re just using their stuff for avatars or backgrounds, then you could probably just check their FAQ for “personal use” and just link to it without asking if they already said it’s alright.)
Stop being ignorant.
Part three is that if you are a person who DELETES sources, then you’re absolutely despicable and shouldn’t even be given the right to look and another person’s work.
Sorry. I really needed to rant about that.
