As already noted in the thread on our being defederated by lemmy.world, we are now refederated for the time-being. However, as noted by one of the l.w admins if there are any spamming issues we'll be back out again and if the upgrades stop we will have trouble with federation (lemmy.one is still not on the latest version, while we are), so there is still a need to sort this out.
My concern is that "Tom" was actually Michael Gambon - which is why we've not heard from him.
