At least it doesn't ask for a response, like "how are you" or "how's things?"
It's just an attempt to briefly acknowledge you're asking a human your questions, rather than an algorithm.
You're presumably capable of seeing and skipping the sentence without reading it, so go ahead. Nobody expects an answer, nor continued "courtesies" during back-and-forth replies.
Having thought about this, I think I will start using Ave like a Roman.
Ave Oxjox!
