A reputation/karma system combined with probability ratings might help a
A central trusted list like dns blacklist would probably not work,
because checking reports would be unsolicited calls for the checked
number and it would produce cost.
Therefore the only method would be some kind of social network thing.
People could be trusted when they submit data that other persons have
also reported. A extended check could check for unrelated clouds, like
multiple persons reporting the same data.
A cloud of reports bound together by multiple persons reporting the same
thing could become more trusted when the same people also reported
sigificantly to other clouds...
But i think spam fighting methods could be added later when the systems
becomes a targed.
What i mean is, not having a working spam fighting mechanism yet must
not mean that we should not start building this system.
I know people working in a social media platform, and they got along
with implementing their spam fighting techniques later, and they tested
multiple methods to solve this problem and are constantly changing it still.
But i'm sure a system like 'i trust someone because i trust that one
because i trust...' (you get the idea...) would be the answer.
In my eyes, trust should be calculated automaticly, not by manually
defining trust (like pgp). Using the system could improve it.
I have better things to do with my life than managing trust relations
for my spam filter...
And by the way. Spamassassin (or better something 'lighter') for sms
sounds like a really really good idea...
Just my 2 Eurocents
PS: This calls for a interception API on the phone. Fighting spam would
not be the only thing that would be nice to hook into these events.
Configurable ringtones for different people, programmable ringtones and
so on come to mind.
Is there anything there yet? Or planned?
