If you are not suspended or disqualified and your node keeps being online on all satellites it should be fine.
I guess this is the current pattern every SNOs or most of them are seeing.
I could imagine that a customer like this could have such a usage pattern.
But it could also be some other customer testing the network (uploading, downloading, deleting) in preparation for migration. Which is a really nice thought.
But really as SNOs we never know. Basically it could be anything.
