[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:

especially the wifis at (0,0) are causing trouble here at Freifunk Nordwest, see

it would help us a lot, if those obviously false entries could be removed from the DB

Kind regards Lorenz
