In this example i will use the [BR-DISK](Collection-of-Custom-Formats-for-RadarrV3.md#br-disk) Custom Format the one most people don't want to download anyway and if you do then you probably don't use Radarr, Plex being both don't support it.
In the empty `Custom Format JSON` box (1) you just paste the `JSON` what you got from the [Custom Format Collection](Collection-of-Custom-Formats-for-RadarrV3.md) followed by the `Import` button (2).
The Custom Formats in the profiles needs editing on 2 spots.
First we're going to set the scores for the Custom Formats and for this we scroll all the way down.
And then we're going to set a score of `-1000` to the `BR-DISK` to make sure it will be ignored for ever and never going to go over the `Minimum Custom Format Score`.
For Custom Formats you really don't want, set it to something really low like `-1000` and not something like `-10` being when you add a Custom Format what you prefer and you set it to something like `+10` it could happen that the `BR-DISK` will be downloaded (-10)+(+10)=0 and your `Minimum Custom Format Score` is set at `0`.
