Most of the ingested stuff has truly ridiculous keywording. It seems to be accepted without any inspection, and certainly Keywordzilla, who removed evening from a photo taken half an hour before dark, hasn't been let loose on them.
I have no idea why they put in so many totally irrelevant keywords anyway. Maybe they use one of the keywording programs or oursource it to five year olds in non-English speaking countries.
And the 'setting the table' bug is back. I found it on several new ingested Agency images. How there's a bug which specifically adds the keyword phrase 'setting the table' to ingested images, I can't imagine.
The badly-keyworded ingested images seem to automatically arrive unable to be wikied and set as 'needs review'. I believe the keywords team is supposed to check them later, but there is a very long backlog, if indeed they look at them at all.
Set Keywordzilla onto them. H*ll, I'd do it for payment (in the Good Old Days, I used to have delusions about working for Team Keywords), but the subjects are boring, so probably I'd just fall asleep.

Which is an example of why nobody trusts them to handle the "simplification" properly.

It's all whacked. We got no idea what's going on under the hood.

This is the reason the best match is so screwed up, IS ingested over 18,000 images in the past week from this Getty Contributor. 

How do those files have more than 50 keywords? Doesn't IS limit us to 50?

They do, but:
1. Ingested files don't need to follow any rules
2. Even us plebs can go over 50 if we can tick two words in a disambiguation. Simple example: say you had 50 keywords and one of them was referring to an orange, you could correctly DA to orange (fruit) and orange (colour) then you'd have 51.

It's impressive work.
