Ask HN: Can BeReal Scale?

I never did any real software engineering, just read stuff, so i wanted to ask HN engineers, what they make of BeReal. The app is really hyped right now, but I thought that it might be really difficult for them to scale beyond a certain point, because of the apps nature and concept. Essentially BeReal has virtually no traffic all day long, with a very high peak at one point with a lot of data. Could this be an issue?
