Hi all,

All of the people involved in sending the survey request have contacted 
me and followed up with the HOT Board.

They have all expressed their sincere apologies for the concerns they 
caused and stopped their current method of contacting people.

Because HOT and OSM in general are always happy to work with researchers 
to the best of our ability while respecting all of our users' privacy 
and good will, we are in the process of figuring out how best for the 
researchers to still collect the data they need using a different 
approach and complete their project.

As I told the researchers: I think we all learned a little here and I 
know HOT will be improving the visibility of how to contact and work 
with us for research projects in the future.
