Well @rgeddes i think it's a great thing to do. To m I think they care about the purity of the human soul.
Swearing does a lot to the person that receive it and the sender also.
It darkens the senders soul and make it hard for him to see the good in his fellow and thus, looses his humanity in the process.
Wish the law could be worldwide at least they will be helping to put the tongue in check.
Im not sure. I think swearing is "arbitrary" on one hand - but I can't deny how much of an effect it can have on those who view swearing as a taboo. If kicking the habit makes me brighten up someone else's soul - BONUS!
By bonus.
We get to see the good news people
