I’m no expert on the process, but I’m pretty sure as long as the process server can attest that the papers were produced to the person being summoned. You don’t have to read it at all… The process server can just drop them in front of you and say “You’ve been served”.

I know that if you can’t be found alternate mechanisms exists, but usually requires attempting to exhaust all other avenues.

But the dude literally outright told the news he knows about it. I’m pretty sure that would be more than sufficient for the court to state that whatever mechanism they used to serve him was sufficient since he knew about it.
