If you're are afraid of using your documents illegally, you must follow follow this steps:
1. Go [Suspicious link removed]] [Suspicious link removed][/url] and type some words as: DO NOT RESELL ,or FOR ICO ONLY on your docs.
LOL and now a completely random site, [Suspicious link removed], has a copy of your legal documents,
before you watermarked them!
Download image editing software on your local machine, if you want to watermark confidential documents.
Best to add a text over your id's or passport like "copy for xxx ICO". So it is pretty useless for other illegal activities.
Really? They can't pay $10 to an experienced Photoshopper to remove that text?
And what about the video verification you have to do for a ton of services? No text/watermark there. The resolution may not be great, but ML-based image sharpening tools already exist and we're talking about very predictable content, like an ID (text) and a face.
