[Openwifi] Garbage in the DB

Hello guys, there might be a little bit of garbage data in the database. for instance the wifi located at (lat,lon) (0,0) and some other wifi that seem to exists offshore of west africa. see this permalink: http://owm.vreeken.net/map/?zoom=7&lat=248286.57709&lon=257401.69271&layers=B0T especially the wifis at (0,0) are causing trouble here at Freifunk Nordwest, see https://map.ffnw.de/#!v:m;l:ec086b741582-f4f26d85a1f6 it would help us a lot, if those obviously false entries could be removed from the DB Kind regards Lorenz
