Moreover - it puts files on lists which have moved heritage template
to the relevant category. In case of Polish contest if the heritage
has its own category we asked mass-uploaders to put the file into the
category without heritage template in file description.  See for
axample:

On the list there are also files with quite proper, but probably too
lenghty heritage number. In Poland the number consist of:
a) the number itself - for example "A-253"
b) the date of registraton for example "A-253 z 18.03.1972"	
c) the name of viodoship which registered the heritage, for example
""A-253 z 18.03.1972; województwo podkarpackie"

Numbers itslef are redundant - each voivodship has its own list
starting from A-1 till A-9999,

so for us this list of heratige without proper indetifiers is rather
useless and completely missleading. For us it is not a problem - as
our jury won't be using it - but it may produce false statistics for
our part of contest.
