As far as I know, and I've asked the same question within Poloniex support: you are NOT prevented from creating more than 1 account, as long as you use verifiable information (meaning, under your own name). In any case, I would always recommend that you fully verify any account you create before depositing anything. Polo has an automated verification for basic level and second level, which means you need sharp and clear ID documentations. But beyond that, it would seem it takes ages - even I've been waiting for months to have my account (newly) verified.
Hello every one, thank you for your info and answer ,
i really appreciate it ! as it said so i can creat 1 more account to try verify it fully. god damn ! my current account seemed to be fucking hell unable to get the point while my friends did that very easily in just a few minutes . WTF
