I know this one guy ... used to be  gurhka smoker ... he subtly asked in a post where one might get some of the forbidden fruit.  
Did I feel bad when I told him?  No ... he seemed like a nice guy from my limited online interactions with him.  
So I told him .... 
www.papayas-r-us.com.  
Now his collection of papayas is truly impressive.  His buying hasn't interfered with mine because he graduated to sites that I have not used:  
www.ripe-red-papayas.com, 
www.nuthin-but-papayas.net and 
www.aged-dunhill-payapas-for-all.com.
But in your case I wouldn't sweat not telling somebody.  They don't understand, well that's just too FB.
