Just letting everyone know.
My account was banned roughly 2 months after I bought gold bars on this forum (yes I bought them from a member and not a gold farming website). I had set up a selling merchant for 20 items from the sundries for 1gb each. Seller did his job and gave me the gb's with no problem.
Be smarter when buying or selling gb's. Sell real items for overinflated prices or you will be banned.
Evidently G1 can track things like that on new accounts pretty well. They will wait for a few months and then ban you without an explaination.
Anyone else bought GB's on a new account then got banned a few months later without written cause from CS?
Only other thing it could have been was the fact that I used a buying merch to purchase BUS's for resell. If you look at my purchases though, you can tell I actually bought them. Spend 145m on 63 of them in a span of 3 days. No hacks here.
