I only just thought of this. I have the same cartoon-y profile pic from a foreign TV show on a bunch of my accounts, I wonder if its unique enough and worth tracking.

Yes, of course they could. Generating an image fingerprint is not all that computationally expensive by today’s standards.
Is it unique enough to track you? It doesn’t have to be, since online tracking generally keys off of a set of data, rather than a single item. But just for the sake of argument, consider that services like tineye and google images have pretty good success at matching images even with no additional data.
Is it (or will it eventually be) worthwhile for data collectors? You would have to ask them.
