Please, i always post on all my drawings:
Do not repost on any social media without permission.
Do not edit or reproduce the painting.
And yet, i find my drawings either on instagram and on facebook, and no one has asked me permission for it.
No, i don't feel flattered, i ask nicely for it on all my drawings, the download pic is disabled for a reason, i don't want my art going places on it's own without me knowing it or allowing it more likely.
Respect the artist, i put effort and time on my art, and if i show it here, is because i find it convenient, but it's just that, SHOWING IT. Not giving it away.
Later you ask why pixiv japanese artist stopped uploading or blocked accounts, well, it's your fault, isn't it?
