Hi Simon,
Consider that this nuisance refuses to answer polite requests to say his name, and will not sign posts. One cannot assume his name is his email address. This luser hiding behind anonymity, come here with the express purpose of disrupting the community needs to leave. Generally lusers like this do after a while, but this one seems particularly offensive, What disturbs me most is that blacklisting the posts does no good as I still get all the replies. The sort of pathology we see here in this type of luser is one where they delight in sucking time and energy out of people, giving nothing in return. Cases like this are sadly quite common on mailing lists and similar channels.
It disturbs me to think that I may have to unsubscribe to this list in order to stop my inbox containing the vitriol from this person.
I know the list moderator never takes steps to intervene, but if he is out there, it would be helpful to all to have something done about this matter.
To the person in question: whoever you are, Phantomas, you are clearly not welcome in this community, despite David Kastrup's ameliorating comments. Stop wasting peoples' energy. Write your own engraving program. Let us see it. Cease insulting the good hearted people on this list. Begone.
Andrew
