URLs in source tags to bnhelp


I noticed you have quite a few of these source tags (a bit over 132.000) like:

Edited over 13 years ago by pavel · Changeset #204763
Location: 49.6791040, 18.0824490
created_by shpupload
source HELP SERVICE - REMOTE SENSING spol. s r.o. http://www.bnhelp.cz

Is the service at this URL still something we want to link to? Is bnhelp a genuine resource?
Attaching source tags to individual elements was probably standard back then, recent edits would place it at changeset.


it is part of very old import. https://wiki.openstreetmap.org/wiki/Key:source
As far as I know, there is no plan to remove them by mass edit.
