Now I understand: I thought that federating Threads was a deliberate choice, but it was probably an incidental phenomenon simply due to the large numbers managed by your instance.
Probably one of the ten Instagram executives who have a federated profile has tried to search for one of your contents. Or he found the message of a followed user who participated in one of your threads in his Timeline. Or they are simply experimenting with your instance...😁
I said the wrong thing here. Excuse me
~~In any case, there is at least one other Lemmy instance, probably for the same reason: it is an instance that handles quite large numbers anyway:~~

Thanks for the mention. This is a very interesting and informative page for all users of the fediverse
