I've noticed in this game that you could send a tell to dfdfs dsfsd and it will go though with out an error message saying this person may be offline or is changing areas.

Another example.
I've tried contacting a few friends and never get that error message nor do I get a respond from them.

There could just be afk, but all the time?

It would be easy for me to know if the tell is getting though or is not because persion is of line or the name misspell.
