First, you want to visit your played games. You can do so by visiting this Link.

Then scroll down to Halo Reach, if you have a lot of games, don't want to find it,
running Google Chrome, hit ctrl+f, and type halo.

Check your last played date,

(Mine was 161 days ago, which allowed me to gain 160,000 credits.)

Then calculate the difference from today, and that day.
You can that through this site:
Link


Mine was, again, 161 days.

Then open Horizon, as well as the Halo Reach credit editor.

Open your profile.

For the number of credits you want to add, insert a number before your given one.
(Mine was 161, so I put 160000) then click add.

Save, rehash, and resign.

start up Reach(OFFLINE) and wallah look at dem credits.
Then connect to Xbox Live, and they should be there.

If you get caught could they console ban you? Or ban your Xbox Live account?

I'd assume it'd be a cR ban or something.. Although with what Bungie pulled over service tag mods i would put nothing past them.
