I usually don't get messages like that when my scripts use stuff like aliases, so I don't know why those are appearing for you. But I think those messages are basically saying that your script uses an alias, which changes data that your script uses (something along those lines).
From what I've looked over, I can't spot anything malicious about it, unless the website that it's connecting to is malicious. But from those messages, it doesn't really suggest malicious activity as far as I'm aware.
(I'm not a pro, so don't take my word 100%, I just say what I think and presume)
