If anyone is making money off this without you getting a kickback, that's simply disgusting.
Though to be melamed zchus on whoever cropped it, when passing something on via WhatsApp, people often crop the screenshot so as to get the essential part as clear and as big as possible on a small screen, with no bad intent or awarness of harm whatsoever.
Yeah, that's why you always see tweets, small facebook posts, etc. with the handles cropped out. /s
*Most* people have no ill intent, they just have no concept of giving credit. The last time something of mine went "viral" I got a bunch of job opportunities out of it. I'm sure if people would realize, they wouldn't crop.
