Seems reasonable that an alien craft travelling between stars might want to illuminate the whole star system to detect dark objects and plot a safe or more perfect course.
Apparently Wow! came from the same area and seemingly was blue-shifted by an amount that could make sense from an approaching craft, so that doesn't sound that silly to me.

Unlikely to be the real cause, not silly.
