For what has sold, do a Google Image search like this. (Excluding the Alamy.com site itself.)
Wim & all,
How to explain Alamy watermark on many despite excluding Alamy.com?
FYI, Tools>Time>PastWeek makes it very current, but produces mostly watermarked images...
Well there's this thing on Reddit, where people put funny text on Alamy pix. Probably on all pix from all agencies. There's Pinterest of course.
For the rest, I would say, why not click on it and find out? I wouldn't know either. A couple of mine appear like that when I search for zoomed images. Most if not all in pretty harmless tiny blogs or legit discussions.
And in some fake news/Russian or Ukranian ladies want to marry you/f* you/Russian image library - leave your credit card number here please - sites. Some of which my virus checker won't even let me visit.
Some of those with pretty high seo scores even. If I have time I file a Google complaint.
Let's hope Alamy can spare an intern once in a while to do a sweep. However I think only the original copyright owner can request removal of the link. Or it's at least much less work.
