It seems like once you understand the nature of the anomaly that it's something you would be able to adapt to. Sara probably couldn't overcome the fear that something bad was going to happen to her because of the MalOs and living under that fear for extended periods of time destroyed her psyche. But William just got used to it, and it's harmless, so he learned to live with it and even began waving at it.

No records of any hostile activity from 1471 or 1471-A exist. So if you were to be affected by it, it would literally be in your best interest to calm down and eventually just welcome it as a part of your life. You could choose to be afraid, like you or like Sara, but it wouldn't help. Alternatively you could choose to embrace it as a benign anomaly and an odd absurdity in the world, as William did. For some lonely people that might even sound fun, so they become fans of it. From fandom stems... all sorts of oddities. But it's easy to see how they aren't afraid of a funky looking dog that sends you pictures. There are much worse things in the SCP world.
