I don't ABing on your main. If you commit an obvious mistake on shell, you
may not get frozen on your main.
You can get away ABing on your main, just remember that any derp moment could mean a freeze. And TNT is mean and likes to take some days/weeks before freezing (in order to link mor accounts that could belong to you and to deny you the opportunity to save anything)
But if you AB on sides, try to not get them linked, that doesn't mean that you need proxies (they help, but you can evade chain freezings if you are careful).
Not linking them means that it shouldn't look like they all belong to the same person.
Don't transfering items/np frequently is the key, but TNT also takes into account if they share IP (proxies
help, but are not tht escential IMO), sharing computer, Operating system, etc.
You run the risk of being frozen whether you use an Autobuyer/Cheat program or not. There are a number of people who (are supposedly) legit and big on the Neoboards who get frozen for 'no reason'. I remember I first started cheating because I was frozen for cheating when I was playing legit.
Yes, setting the settings to mimic human behaviour (not necessarily yourself) you are indeed lowering the risk of getting frozen.
Yeah, TNT has a weird frezing system. However, all the supposedly legit people that I've seen getting fozen (at least if they were botting they were really discret and not greedy) always ended getting their accounts back (after months, but they got them back).
I've been chain-iced before too... yet still had some accounts stay safe (even though they share the same IP and all).
Ditto
IMO proxies are only worth if you are really going to AB on multiple accounts (lots of them)
