I noticed today that most spots of stations reporting W0EJO/4 on 30m yesterday are no longer in the database.

I remember seeing many spots of W0EJO/4 while browsing the 30m spots yesterday morning. But now, only 14 of these spots remain.

On 2016-10-27 between 13:44 to 14:52 I have 148 30m spots in my all_wspr.txt file.
The wsprnet database (and archive) only has 144 of these now. The 4 that are missing are the 4 spots I made of W0EJO/4.

161027 1406 3 -14 1.9 10.1402050 [W0EJO/4] EM85 30 -1 1 0
161027 1422 3 -18 0.6 10.1402034 [W0EJO/4] EM85 30 -1 1 0
161027 1432 5 -12 0.8 10.1402032 W0EJO/4 30 -1 1 0
161027 1440 4 -15 0.1 10.1401927 [W0EJO/4] EM85 30 0 1 0

Any ideas on why my (and many other reporters) spots of W0EJO/4 were purged from the database?
