Keyword spamming being rewarded

It looks like keyword spamming is being rewarded by the Shutterstock search. If you search under best match, images with a repetition of the search word in the title are pushed up in search. Here for example

https://www.shutterstock.com/search?search_source=base_landing_page&language=en&searchterm=frog&image_type=all

Almost every image on teh first page has frog at least two times in the title. This phenomena you can find for other searches too. I thought keyword spamming was not allowed and now it seems to be rewarded!
Something is wrong!
