Could I cash out all my chips, uninstall my poker room software, sign up under a new name and get a bonus for a first time deposit using the same software, reinstalled?

No, most sites will know your computer and IP already have an account. If you get caught they will likely seize all of your money. If the poker room you like is on a network you could sign up on a skin. For example there are endless Prima skins and many Crypto skins and you can have accounts at all of them as long as they don't ban your country.

This answer depends on which poker room you are playing through. Some (full tilt poker), you can actually cash out your money, and without having to uninstall the software, just create another account and receive the initial first time deposit bonus of $600. Of course, you have to use a different email address than you used to sign up for your first account.

Where did you learn this? Many have tried this to get rakeback and have ended up in a nightmare with locked accounts.
