I'm just going to be vulnerable for a minute here. I met the first person in real life who had similar server-y linux-y obsessions to me and we'd send eBay links of systems to drool over to eachother. They ended up being a terrible person but hid it from me pretty well until they couldn't anymore and now I no longer have someone to chat with about those things.
So um, I guess I'm open for applications for the position of "nerdy friend who I nerd too hard with about network infrastructure and Linux packages" now

Sorry bud.
Though this got me thinking can there be a specific message to a specific user attempting to login (and deny their login)?
You could create a login banner and just delete their account
