Unfortunately no one can prevent another from buying a HAM radio and using
it for malicious intent. Same goes for APRS, and when someone is detected
abusing the service typically HAM's pull together find the abuser and report
them. OpenAPRS validates HAM's based on their callsign and then locks their
abiility to send messages to only the callsign they signed up with. I'd be
happy to open up the autentication system to act as some sort of OpenID
system that works for APRS-IS servers as well but that is up to the powers
that be. I've never been unapproachable about things.
The responsibility can't be placed on the "web developers" for an inherent
flaw in the teir server software, we've done the best we can to prevent
abuse but as you stated below it is an imperfect system. All messages,
objects and position reports are logged that come from OpenAPRS so tracking
abuse to an IP address is simply an email away. The true responsibility for
this issue lies with the APRS-IS server operators however, as stated before
I'd be happy to assist with an OpenID sort of standard.
