MapDust - which apps creates those bug reports?

Hi,

On http://www.mapdust.com it seems as a lot of openstreetmap bugs are visible. Do you know what programs/apps are used to create those bug reports? Are they created automagically when running navigation apps or do users have to post them manually somewhere?

Thanks in advance,
Michael

Skobbler’s GPS Nav2 App is one, and I believe reports filed from the Mapquest/Open web site also go there.
