Add Mastodon-style custom profile fields / Add `rel="me"` to all links in bio.
Can be either links or plaintext. Mastodon allows a maximum of 4 such fields. Example:

Flairs would be better than nicknames
This is basically done, we are just missing the 4 link fields. But I dont think thats important, I've already seen someone reproduce it with a markdown table. So I'd say we can close this issue.
No I think we need this open, because those special URL link fields can be used to verify identity:
IE like <a rel="me" href="https://mastodon.social/@dessalines">Mastodon</a>
Okay, but might be worth to open a new issue specifically for that identity verification, because it would need some additional work which isnt mentioned here.
Unnecessary.
Sorry to comment on a closed issue, but would it be a good idea to automatically add the rel="me" tag on all links in the Lemmy bio? That way they could be used to verify Lemmy accounts on Mastodon profiles without having custom URL fields like on Mastodon.
That re-writing would probably be best in lemmy-ui. I'll re-open and transfer this.

I think this would be a very good feature, especially for the verification part since as things are now, it is frighteningly easy for people to impersonate others. Having verified links just like Mastodon does would greatly help with this problem since you can make it very hard for people to impersonate you by linking your website, blog, or main account and having it verify your account.
Mastodon only adds rel=me if the linked website also links back to the same Mastodon profile, to ensure that it belongs to the same user. There are also some additional validations: https://docs.joinmastodon.org/user/profile/#verification
So this would definitely require a new backend feature. Specifically it would have to perform the same validation steps in save_settings.rs and then add database, api fields to indicate which links are verified.
