Re: line conditioner

A persistent troll who searches the USENET archives daily for
posts about his pet issues (lightning strike, power
supply, UPS), just so he can go into that group and reply, without
references, as if he knows something. Unfortunately, he provides
lots of misinformation. However, his trolling is most useful in high
end high-tech groups (like sci.electronics.design) when regulars
don't recognize him and put well-written effort into refuting his
nonsense, and makes for some good reading.
