No it doesn't, and never did. It's not like it was Dalnet's fault that some idiots attacked them, and the same would happen if they chose to attack any other network. well, actually other networks have hopefully stepped up their security now, but from being the largest IRC network in the world, I don't think Dalnet would have had the worst security in the world.
I think Dalnet was wonderful, with certainly my favourite services of all networks I've been on *grumble gamesnet grumble*, but that might just be from four years of being on Dal. :-)
