Poacher is, I believe, the bot that comes with the WWW:Robot module from CPAN in perl, at [perl.com...]
Lynx is a text only browser available on *nix platforms.
The Poacher IP you have is most likely some dsl user testing out their bot creating/ modifying skills.
The IP on Lynx you have is probably more or less the same. In your log files, did they grab robots.txt? You can usually tell "legit" spiders from fake by checking on this. If they do grab robots.txt, then they are more than likely not somebody just playing around, as I suspect Poacher was doing.
