Mass Twitter Accounts + Unique URLs

i have just created 20 accounts.
should they all have different shortened URLs in the URL Fields?
im sharing 3 accounts per 1 ip


and if not...will all accounts be flagged?

thanks

I tried using short urls in the URL field but wasn't able to. And I just got another 5 accounts suspended in one swoop, so I'd be interested in any way of preventing that from happening again.

yeah i just got 50 accounts suspended.
but they all had the same URL and same Description, same BKG.

Different Usernames and iPs..

i think twitter is changing their algos..and cracking down hard.
those accounts were live for 6 months.. and following 400/day

any fullproof methods out there that are working for NEW accounts?

thanks
