Ah, yes, this is quite the conundrum. What I suggest you do is to go to the address located on the brochure while dressed in a single white drape with a full beard (fake if you need help), and a cross with the brochure taped to it. Walk to the front of the crowd and scream to them, "Brother, sisters! I have come to return what belongs to you!" Then promptly leave , making sure you left the cross behind so the entire crowd is dumbfounded.
Or you could just throw away the brochure and continue with life like 99% of the other population does.
