Question about Amazon affiliate

I was registering on the Amazon affiliate but stopped when they say i must insert my website's url, i want to understand something before:

1) if i put an url and then i'll change in future the affiliate still works?
2) could i put my affiliate link on multiple sites at the same time? i own 2-3 niche sites, do i need an account for each site?
3) could someone buy straight from an affiliate link? es. my friend need something from amazon, i paste my link in chat and say "here, use my link"
4) could i buy something i need on amazon with my affiliate link or not?

i read Amazon ban for cookie stuffing, i don't wanna to do this but how can they detect if they are stuffed or not? i'm scared that using straight links and multiple website will trigger they like a sort of stuffing, or not?

thanks in advance for the answer

1..You can add and delete sites in the control panel.
2..Yes just add the sites.
3..No friends or family can buy it against the TOS.
4..If you buy something it will show up for a day than disappear.

I wouldn't attempt cookie stuffing they will ban you.

have you read what i've written?

As for friends and family buying they look for last names, zip codes, and so on that will create a pattern if they buy often.

You may be able to get a few buys from friends but once they see a pattern it will cause problems.

If you buy an item with your affiliate ID the item will show up in ordered items for a day then disappear. They know its you so they remove it.

The only way I have ever heard of cookie stuffing is with a script. So unless you purposely run a script to stuff your affiliate ID in browsers you should be fine.

There were some guys a few years ago who cookie stuffed Amazon and eBay affiliates and made millions before being caught. http://marketingland.com/cookie-stuffing-could-land-ebays-top-two-affiliates-in-jail-42336

I'm not saying your cookie stuffing, I'm saying you should have no problems unless you do it on purpose.

alright, now i understand, thanks!
