Everyone knows that mailing your stolen money straight to your main is risky, and even sending it through several decoy's (lvl 1's) can still get you caught.
Assuming that you are a high rank in your guild...
Step 1: Get a guildie to invite the hacked account into your guild (Tell them you're having trouble inviting them).
Step 2: Have the hacked account deposit all of his (good) things into the Guild Bank - Items, and money (Then leave the guild).
Step 3: Straight after, log in with your main, take everything he deposited. People may suspect you for stealing from the GB, because it will say "(insert your name here) has withdrawn 5k gold from the bank" but this shouldn't be a problem if the "(Hacked account) has deposited 5k gold" message is right under it, your guildies should know that it was planned, and won't assume that you are a person who steals money from your guild.
For extra security, withdrawl and input a bunch of really cheap stuff, like linen, or a few copper, to clear your little "Trade" from the bank logs altogether.
If you are not a high ranking person in your guild, you can always make an alt and have him start a GB, (its only 100g, which is nothing compared to what you'll get), and, after the whole ordeal is done, you'll have a char that you can use as a bank. This is also useful because you won't have any snoopy guild members getting suspicious. Just pay some level 10 noob with no guild to join it and invite your hacked account.
This is my first post and I haven't been here very long, so forgive me if this has already been posted.

The only problem is the IP, which can be fixed by spending 5 minutes in Starbucks. (If you have a laptop.)
