I put an image of my email address and my cellphone number in my ...

An image is a little harder for automated systems to read, but some scammers have been reportedly using automated OCR to extract the text.

Even the "mangled images" that are so disorganized that a person who is color blind may not be able to read them have been broken.

OCR that can read out-of-line multi-colored images is claimed, but a simpler method appraently used during a recent international soccer(?) event to scalp tickets involved "blasting" a copy of the image to a few hundred email addresses with a "enter the numbers to win a big prize" message. If even one person answered within the timeout for the "ticket order" the answer would be automatically entered to buy "more tickets," giving the scammers the ability to buy large blocks of tickets fairly rapidly in violation of limits on order sizes or "automated ordering."

Strong encryption is about the only reasonably safe method of preventing your info being lifted by the criminals, and there are a number of "data vault" or "password vault" systems available for the stuff you keep on your own machine; but of course that's useless if you actually need to make information available to "unknown others."
