Help with adsense content display

I run an article directory and adsense was displaying the correct ads for each page,

but lately the majority of the ads have been about make money, make money, make money - which is very annoying when the articles have nothing to do with that key word.

 

you need to filter such sites within your account

 

I'm not doing that for 5000 articles. And in the finance category etc the make money ads would be relevant - but not in the sport, travel, ... etc.
