General :: Audit Of Root Exploits And Unofficial Bootloaders

This is a general question that should be in everyone's mind who might want to root a phone or tablet or any Android or other mobile OS device:

Is this root exploit or bootloader going to be spyware and collect any and all data of mine (login credentials, keylog my every character, account/bank numbers, identity information, use your evil imagination)?

So, I searched this forum for key words like "trust root" "secure root" "security" and found nothing related to this topic.

So, how am I to trust ANY of the root exploits or bootloaders created and posted to this forum for ANY device?

Have any of the developers developed an audit process using firewall rules to ensure that a posted root exploit or bootloader does not attempt to keylog, report captured information to some obscure IP address (thief/hacker's machine of course)?

Do any of these root exploits or bootloaders or custom unofficial builds of entire android (like Cyanogenmod and the 3rd party variants) get Security Audited?

How am I to believe that the whole lot of you making the root exploits and bootloaders are not a big community of identity thieves and financial fraudsters?

Am I just supposed to trust you?
