[dp-tf] unreferenced person/role object stats

HI

The RIPE NCC was asked to investigate the increasing number of
unreferenced person and role objects in the RIPE Database. This is
personal data that is not relevant to the purpose of the RIPE Database.
We have now done this investigation covering the last 5 years. The
results were surprising.

We found that one organisation is responsible for most of the
unreferenced person and role objects created in the RIPE Database this
year. They are also responsible for a large percentage of the
unreferenced person and role objects created in the RIPE Database over
the last 5 years.

These are the actual figures:

organisation X unreferenced person/role objects created compared with
total unreferenced person/role objects created for each year.

year      X    Total
2007   109031 134986 81%     (Till October 31)
2006    13188  51393 26%
2005    13139  56006 24%
2004    12841  78204 16%
2003       98  38656  0.25%  (from June 1)

Total  148297 359245 41%

Current total unreferenced person/role objects is 553572
of these 26.8% are from organisation X

We have contacted this member organisation for an explanation and asked
for permission to delete all these objects in one step.
