How many acc. with links to one website?

I was wandering how many Twitter accounts can post links to the same website legitimately? I am talking about spun tweets with unique shortened links and no more then 4-5 accounts. It's impossible to find out from Twitter TOS but I know that "Serial accounts" and "Cross posting" will get you suspended.

Is there any tricks to avoid problems? Should every account have it's own domain with redirect to the main site or subdomains will be enough?

Example - LeapViral is using a lot of affiliate accounts to post the same links to about 70 articles only. Their Alexa is 74k and I guess they are earning good on Adsesnse. Do they have separate domain for each affiliate or what?

Any input will be greatly appreciated.

It doesn't work like that but you can use clocking link or you can post on one account and retweet on the others

Why it works on LeapViral and "doesnt work like that" on my site?

So... do different link shorteners work? Redirects? What's the current status on best approach here?

I've found out that LeapViral creates separate subdomain for each affiliate but their main domain is blocked now by Twitter. Anyways it should be much more then 3-5 accounts posting the same tweets to one website. May be in a case of your own site these 3-5 accounts should not follow each other not to look like serial

I dont see the problem here. It act like your friends are tweeting the same link
