multiple accounts?

would they ban me if i use same Bank account for withdrawing on more than 30 CJ accounts?

I would advice to contact CJ directly with anonymous name and email address. Ask them as if you are a newbie and wants to clearify this qs.

I had no idea it was possible to have that many accounts.
Why are so many needed? Surley they would sence something suspisious and maybe ban them all?

If all accounts are under the same name and address..then go ahead you'll be fine.
If there not, well.. Ask them just to make sure (under anonymous email of course)
