Multiple accounts, don't use the same account more than a few times...
out of curiosity, how much GP had been traded on that account?
Could buy r2p's guide on how to avoid it (I don't own it so I can't speak on its quality but it is r2p...)
I thought if you put your gold in the ge they don't touch it?
It's somewhat luck. I moved 10b a few days ago, straight trading, and didn't get erased. What I'm doing from now on though is staking GP, world 54. I've never heard of a staking-only account that has gotten erased.
