Tai (UFLTAI@MEMSTVX1.bitnet) asks about how best to stop people from generating many, many digital pseuodonyms, thus evading filtering by "Kill" files. Lots of issues here. The longterm solution is to use "positive reputations" and not just "negative reputations" (as in Kill files). This is something Dean Tribble just talked about at our last physical meeting of the Cypherpunks ("Bay Area Branch" :-} ). Think of like a credit rating. People _earn_ trust, they don't just get assigned a credit rating until they do something bad. Positive reputation filtering will still allow digital pseudonyms, but a reputation will be attached and will be important. Read Vinge's "True Names" for some insights on this. --Tim -- .......................................................................... Timothy C.
