Edits, since there is no preview feature. I said I'm at-pwinn-at-qoto.org initially, but with @-symbols in place of the "at-" strings, which mastodon helpfully rewrites and links to make the narrative look odd. In fact, I cannot figure out any way to actually include my address as text. Wrapping it in backticks didn't help.
Also, when I search for my friend's @username@server identity, it finds them. Not sure why it didn't for them in reverse!
@barefootstache Oh, right! I saw that qoto.org is on the hachyderm list, not sure how widespread use of that list is, nor why it's on there exactly.
Ah, mastodon.
@pwinn the main reason iirc is that on qoto you have free speech which lots of other instances don't like. E.g. here you can swear, talk about genders, bigotry, and any other topic openly. This is frowned upon most of the rest of the fediverse.
There are only really a couple of options forward: either you or the other party can migrate to an instance, where this issue is prevalent. Or you could create a secondary account that is in the regulated speech cluster.
@pwinn if servers are not connected (federated) then it can be that certain information is not provided.
Qoto.org is known to not be federated with lots of other servers because the rules of the server don't align with rules of other servers.
