Over on Twitter I stumbled across a new account posting works from other users that they are claiming to have made themselves. They're editing out watermarks to try and pull the wool over people's eyes. So far I've seen two works from others that have been posted and attempted to claim. They wound up blocking me after confronting them about it and having the ability to post the source content.
I don't condone harassment, but I feel that everyone should be aware.
