L'ajout d'un lien externe au champ "Reason" (badge) échoue silencieusement

Hi @dax ,
I have created PR for the same. I just wanted to confirm only links have to be allowed in reason, right? Plain text is also not valid, right?

FIX: throw error when link in reason for grant badge is an external link

Thanks
