I dunno. Does he ever post anything other than "CAn some1 u/l to my server?" or "Is this on my FTP?" or "WHO has [completely non-K-related track] and can encode and u/l?"? Yes he did. He has contributes and helped out lost of people also.
Did he inspire a week-long argument on this list, the most divisive I've seen in eight years here, that was settled by collective agreement on him using the prefix? There were more heated arguments in the past. I remember the period of one person posting about 120 times "STOP THIS NONSENSE" on the KLF mailinglist because of some small fight. That was much worse than this. Second, he did not "inspire" anyone to do so. If a computer game inspires you to kill people, it's still *your* fault, not that of the game's creators.
In the months since that agreement, did he consistently fail to do so? I never saw him agreeing on anything. An agreement is usually made between two parties, of which he wasn't one.
Deleting it isn't the problem - hell, months before the listwar, I'd already gotten fed up with Mr Stringer's endless, illiterately-phrased pleas for people to steal music for him and filtered his address directly to trash at home, so I only see his posts when out of town or checking my mail at work. And even then you bother to bore us with your nerd-like mailing-list behaviour 'rulez0rz', or whatever you guys call it.
The problem is that a situation that disrupted the list terribly and led to the departure of at least one long-term, usefully contributing listmember had a solution democratically proposed within the list and accepted by Mr Stringer. Still this is a problem of that one person leaving. I have joined this list for KLF, not to learn about mailinglist-trivia-nerd-rulez0r-stuff.
If it didn't upset a lot of people, then there wouldn't have been the listwar in the first place - but as other objections by people who don't filter his posts (and remember, the whole point of the [FTP] prefix is so that people who still want to read his biannual on-topic posts [such as, say, telling us that Cressida is actually P.P. Arnold] can FILTER THAT PREFIX) indicate, he's still, through carelessness, stupidity or wilful desire to give people the shits, not doing it. Let us count the number of people who really are bothered by this issue at all... eehm... 1?
