Yea, there's two way you can do it mate. You can create multple Paypal accounts so that each AC account is linked to a separate PP acount, or you can link multiple AC acounts to one Paypal account using different PP emails.
Creating multiple PP acounts is risky in that you don't want to screw with PP, It's much easier to deal with an AC account getting flagged than it is a PP acount getting flagged (or banned.) With all AC accounts linked to one PP account you run the risk of AC looking into your PP account and seeing all emails leading to one name.
I personally use the second method. AC is a non-issue to deal with a flagging compared to PP.
But those are your choices mate.
To play it safe, yes use a proxy or make an IP change.
Good luck
