I got my silver Translator medal yesterday. Of course, it was about a month before I started glyph hacking, so I was a late bloomer.

Seriously though, you get 750 AP for every field that you knock down. This is less than you get for putting a field up, but those blasters need to go somewhere and into enemy portals is the best place. :)

And once you capture those portals, you can relink them yourself.
