multiple accounts on poker sites

A possibly a dumb questions from a semi-newbie to online poker....

All the major poker sites seems to have a strict policy about NOT having more than one account per player and in the case of two+ person households who each have different people playing, requiring that they each have separate sources for funding those accounts (bank accounts, credit cards, ewallets, etc.).

I guess I can understand how that would help prevent collusion. But it's clear from a bunch of threads here that people in fact do have multiple accounts at the site they play.

So the perhaps stupid questions is ... WHY? Why would someone want more than one account? (...that is, outside of collusion or running multiple pokerbots, which obviously is against their policy.) What would the benefit be otherwise? Thanks.

I don't think many have multiple accounts on the same site. I would think if they do, like I have with Full Tilt it's because I arranged a new one to get Rakeback and never used the old one again. Multiple accounts on different skins of the same network are to clear multiple bonus's and are usually allowed.

It can also be used to give your opponents different impressions of your style of play. If you know what i mean...

OK, but if you did open multiple account how woudl you fund them? For someone like me, I've got one bank account I'm willing to use to deposit (+ one credit card, but I'd rather not pay the interest of a credit card on top of the rake.) Like I said, sites are all very clear about not allowing multiple accounts and/or using the same $ source to fund your account. Wouldn't that pose a problem here if, like me, you've already deposited once using that source?

why do you need multiple accounts?

No allow.

I guess it only makes sense for rake back. I made the idiotic mistake of initially depositing $50 into the two sites I play when I could have afforded more and gotten a larger rb. But I was sure if the reason why people do that in general was just for that reason or something else. Also, I played poker a while ago, took a good long break, and am playing again under the same name. I dunno, just wanted a fresh start. Oh well. Thanks.
