Sorry but what's his mastodon account? I can only see this stupid blocked message:

> Promotion of alternative social platforms policy
You may be able to load it via one of the bigger instances, though. Try going to https://mastodon.online/@paulg@mas.to.
Is this always possible or is there a certain requirement, for example that this other instance has pre-fetched the posts beforehand?
