Unless Jagex has some kind of client-side detection for injected code, you won't. Dreambot uses the standard client, it's not a custom client. From the server perspective, I believe they cannot tell the difference whether you're playing with dreambot or not. If there's any kind of client-side detection (which I believe there isn't, can't tell for sure though), your accounts are doomed since the first day you started using DB. If Jagex implements some detection in the future, you will eventually get banned. Otherwise you're good.

I believe any bans related to using non-authorized client will be 2 weeks long at first infringement (Unless you've been botting, which is not your case). Perma ban if continued infringement.

What requirements are we talking about? I believe DB3 would take the same approach as DB2 (injection if I'm not wrong) and unless there are some specific mechanism to detect injection, Jagex cannot differentiate DB2 client from their standard client.

For every quest, the first thing the bot tries to do is to pick up my money in the Grand Exchange bank. After that it doesn't do anything.
