Well they make pretty nice cash showing adds. Each time you move they show new ones. Hehe you get 600 moves per day
Even if we say they get like 1 cent per one its 6$ (probably they get less per advert). Its quite big cash even when they give money for refferals and so on.
They have lots of oportunities to spend in game cash instead of payment. Most of players probably dont up to those 25$ at end of month, but they still view all addds
@Col- well i try to think of as many passes i can so there is no way, but still sometimes use same ones. For example my e-mail, i have it on forums like these one or others. I rarely use it at non trusted sites, but still got huge amount of spam. *checks* I have 316 normal e-mails but 276 spam e-mails

Good that gmail have spam filter
There are many sites which use your passwords, usernames, ip's and e-mails. They get those info in so many ways... Thats why everyone should be as secured as they can.
I have nice way to secure passes (as long as your comp is private and no1 would see them). I use yellow sticky paper

They include list of minor passes i made up when i was bored. The most important i of course store in my "biological hdd"
