Yeah, it is probably a test account, but a test account that is somewhat plausible. I don't find 5 or 6 messaging apps unlikely and I see people with a lot of them, because there is little perceived cost of installing more and it improves reachability.

Like, I have Threema installed, even though none of my contacts use it. But if one does happen to use it in the future, I'm reachable if necessary.
