One of our Naruto wiki authors cuts gifs by hand — and started watermarking them himself, because people take them without asking. Now the platform does it for everyone at once.
Two layers — a faint grid across the whole frame, plus the project address in the corner for wiki projects: crop the corner and the grid stays
Personal stays clean — avatars, backgrounds, logos, chat attachments and support screenshots get nothing
Scaled to the frame — on a small image the line is shorter, on a big art it doesn't grow
Quality untouched — the mark goes into the same single compression pass as before, the difference from the original is under a percent
Taking it is still possible. It's just obvious now where from.
