The rejection said "Titles may not contain camera name, web address or other unnecessary info." This was a first for me. Oh, by the way, one photo was named "Pierogies for Dinner" and the other was named "Plate of Pierogies."
This comes up from time to time. I think it is a glitch in the SS software. I got a rejection last month for naming a plate of food too, and was told not to put camera info in the title.

There was a short thread on the forums about a month ago too, complaining about these rejections.
That said, Shutterstock has great reviews generally. They tend to finish reviews within a day or two of uploading (iStock takes 6-8 days for independents, StockXpert seems to take longer and longer). And their acceptance/rejection decision is generally a pretty good predictor of image success. I've had rejections there which were accepted elsewhere, but rarely sold. Most of the images they accept from me, on the other hand, sell very well at SS and elsewhere.
I am a little biased though, since they make me so much more money than anyone else.
