[Dxspider-support] Some information

[Keith, G6NHU]

I’m seeing spots coming in via nodes running build 568 that are being flagged as bad.

As build 568 now has $DXProt::sendverify set to 2 by default, does that mean that the sysops have added an entry to startup that sets this back to 0?

If we’re going to take steps to secure the network and the data we pass, this sort of thing should be hard-coded!
