Agreed. |

Agreed, because of the way the subscription process works. The way how |
20 |
someone subscribed to a list is _only_ with a e-mail address. This would |
21 |
change if the subscription process would demand a signature. |

Agreed. |

32 |
No fully agreed, because if someone is signing his messages, all other |
33 |
subscribers have the possibility to see whether it's the same person or |
34 |
not. Not in the sense of real live identity but at least same Nick or |
35 |
Name. In my case for example "Wolf Canis". Would know a message reach |
36 |
the ML with my Name but no signature or a different signature, could one |
37 |
relatively be sure about the fact that this particular message is not |
38 |
from the original "Wolf Canis". |

Except if the message is malicious, abusive etc. |

55 |
Why not? Every public key is downloadable, except one created a key |
56 |
and forgot to upload the public key, in this case is his/her signature |
57 |
pointless. |

64 |
|
65 |
Agreed but I would say that we have to differentiate between real live |
66 |
and virtual live. Both of them can or can not trustful. |

71 |
|
72 |
Disagree, because of the possibility that without signatures it's |
73 |
relatively easy to bring a subscriber into discredit. |
