Can’t add anything else to the discussion, i know too little about it. But a US tm is not legal in the EU without separate registration. But i would not waste any energy on it. The value is in the community, not in the name.

What would that mean? I think not much (but not a lawyer)

How does that work in the US? Since e.g. in the EU you can trademark everything and anything you like no questions asked almost. But it doesn’t mean anything if someone will dispute it. It doesn’t give you any rights or guarantees.

Just saying that 99% of users will not get this part of Lemmy. It will split all users across multiple communities where most will not even be aware of others.

I can be totally wrong, but this is my gut talking.

I think this is going to be the main bottleneck in the end. The principle of it might be great, but too many people won’t like this hurdle i’m afraid.
