well i hope you posted all that yourself and not copy and pasted its a good guide except for the clean up part and not getting banned in the process what you will want to do is.
1. "sell" the primal fire to your alt on someone else's account (you need another account avoid getting banned on your main)
2. laundering the gold to your main is best to avoid getting banned
Remember that deleting the character and WTF folder does nothing but make you feel safer. In the end this guide is good just fix the clean-up part because like i said deleting stuff won't stop blizzard from tacking you. Finally take a look at my sig there is a good laundering guide in there. good guide =)
