The "ads" -- actually, Perl-related public announcements are aggregated by an outside entity (whose principals may likely include one or more Monks) and posted here using some code yitzchak provided. TBOMK, any seeming relationship between your location and the advertisers is purely concidental.

However, as to your second question, can you generate a map to show their distribution around the globe?, the answer is "Yes" ...and it's already been done as a world map with monk locations marked. Unfortunately, the server appears to be down, or I'm looking in the wrong place.
