Anonymous notes

It seems that some notes are not added by users, but for some software in anonymous mode.
Example: http://www.openstreetmap.org/note/207882
Most (if not all) are wrong notes about the maxspeed.

¿It’s is possible to identify which software is adding these notes?

There was a thread on the OSM-talk mailing list about these notes recently:
