You know what to do here 
I wonder how long it will take until Amazon shuts down accounts with multiple e-mail addresses, especially with the purpose to gain free trial Prime memberships. I am pretty sure they will soon have some kind of algorithm / artificial intelligence installed to identify accounts doing so.
A friend of mine got permanently banned this way, so I wouldn’t do it. He is no longer allowed to sign-up, use or deliver shipments under his name (unless someone else delivers to him). Not being able to use Amazon is a major issue because sooner or later there will be a sale for any hobby you have or a product you need.
The risk is not worth it IMO.
I deleted the post, but guys, it’s not prohibited. I stated that pretty clearly and referenced the T&C. Only sellers are prohibited from making multiple accounts. It’s not a new idea. Amazon is not waiting on some algorithm technology to catch it. It’s ok. Your friend is apparently the first and only person on the internet to be banned for this including people who have done it month after month for years. :person_facepalming:
