Did they even upvote @Drutter's post? If they did, it's so small I can't see it. Are they trying to advertise something for themselves? Do they even know this is for a good cause? I'd say it's spam, but at least they mention...
"If you do not wish to receive a message from us, respond "Stop" and I promise not to bother you anymore".
And since they also say "We only want to share the Bible and Love with everyone", I'd definitely say STOP!
