There is 2x settings as well

I don't see any POSTs from these IPs in node.sl.o apache log
(posting to node.sl.o requires keys auth implemented in sugar client
library) but all POSTs came from network.sl.o (wich works w/o any auth).

SN was a research project and I didn't think it is still in use in the
field. Having open network.sl.o (and current auth implementation
for node.sl.o) was fine for development stage, but not for now.

So, you can either disable network.sl.o at all or switch it to RO mode.
