Lyn could use @lynalden.com as her Nostr address to help alleviate any confusion as to which Nostr npub is the real deal.
Discussion
That's what I do. It's a good norm - people using domains they own to prove their identity.
What’s the easiest way to do that?
I link to my real profile on my website. People who lose money on these scams rarely bother to check basic details like that. 
NIP 05
Needs well known hosts on your website.
Details are listed here: https://github.com/nostr-protocol/nips/blob/master/05.md
The self-hosted option is best, I think: https://nostr.how/en/guides/get-verified#self-hosted
If you are able to drop a JSON file somewhere your domain can serve, you're good.
Having your nostr profile linked from your personal site is a good runner up!
You need to host exactly the following JSON file at https://lynalden.com/.well-known/nostr.json
Then you can update your profile with the NIP-05 address "_@lynalden.com". The underscore is a reserved name to indicate that you are the domain owner, so it will simply show as "lynalden.com" in clients (as opposed to something redundant like "lyn@lynalden.com").
(eab0e756d32b80bcd464f3d844b8040303075a13eabc3599a762c9ac7ab91f4f is your public key in hexadecimal format)
Hey nostr:nprofile1qqsw4v882mfjhq9u63j08kzyhqzqxqc8tgf740p4nxnk9jdv02u37ncpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsj0xvsn This is the correct answer to your question.
While you're right, many people won't check a website before talking with you, this is a direct visual identifier while in th process of communicating with you. It definitely won't hurt.
If you need help setting up this up on your website with your web host, let me know.
NIP-05 creates more confusion than it alleviates: nostr:note1sznq6ry8uvnwt2xrg82298kha6kd40fxm9gv2g3lgmjup2fyfxyq7lv5k6
🔑 Npubs are enough. Show 'em, Mine 'em, Colour 'em.
If I know that Lyn's website is lynalden.com then how would seeing that domain attached to her profile add to confusion? I understand that someone would register lynallden.com and use that for scamming and I also understand that not ever single client shows a Nostr error when it's invalid. The first one we can't fix, but reading and paying attention helps here. The second one just takes more lobbying from all of us to devs to do some basic validation. A Nostr address is not a perfect solution, but it's miles ahead of doing nothing.
This is all you need to identify the nostr:npub1a2cww4kn9wqte4ry70vyfwqyqvpswksna27rtxd8vty6c74era8sdcw83a you're looking for:
Nothing about this needs permission from anyone:
Everything about this is 💯 Nostr.
1. Npub: colour + last 6 charracters (can be mined if she cares about having a specific one)
2. Followers: tailored to the user (can even be adapted to where the user is coming from, podcast link etc...)
NIP-05 on the other hand:
1. Only "works" for popular profiles of which the domain is known, that have enough high signal followers for it to not be a problem in the first place
2. It clearly doesn't work at all for the people that are being scammed right now by the fakes of those popular profiles. They are too lazy to check and would be way better of with an imposter warning (provided by a free market of services).
3. It doesn't work for censored profiles. Good luck keeping your Neo-Nazi childporn NIP-05 ID.
4. It makes Lyn's followers think NIP-05 is the most important ID and that they also need one asap. Only to then find out only a fraction of Apps actually properly displays it and even less actually verify it.
5. The Apps that do display it everywhere you'd need it end up either bloating their UI or hiding away the actual Nostr native things, for a "later" educative moment they never get too.
6. And then their normie friends will start telling their "email" doesn't work 🤣.
7. It takes extremely precious time and space away from showing users what makes Nostr so unique, powerful and fun: Keys, Zaps & Interoperable Hosting (Relays, Blossom, ...)
8. It sets the door wide open for things like custodial bunkers with NIP-05 + password.
NIP-05 doesn't solve anything. It is miles behind in permission-land.
+1 nip-05 is great for this case.
This was the guide I followed to set mine up https://stacker.news/items/145928
