Concerns with duplicate keywords within campaigns

[Tom]

Say I have a yahoo account set up for nothing but dating. I have say one campaign and 20 ad groups. Everything is fine, but I want to add more keywords, so I go to wordtracker and get another 20k keywords and want to do another 20 groups. Obviously there will be many similar keywords between the 20k I just pulled from wordtracker and the 20K that I have already in ad groups...

Should I take the time to make sure that all keywords are unique or should I just throw them in there, as I am sure that some of those duplicates have been declined already?

Something I'd like to know too.
Hope the experts can clarify abit about this.

Just throw them in there. If they're exact duplicates, Yahoo won't add them.

Even if they are in different adgroups? I have seen otherwise

Don't worry to much about them, your going to do it, no matter how hard you try, its going to happen :) Doesn't hurt anything at all.
