I've started botting on EU, was leveling a fresh account /w kicks, only lvl ~70 when I get banned due to abuse of economy... The ban reason makes so sense, since I has just leveled quietly to this point, so I email blizzard the business 'wha no idea what's going on whaa' and they unban my account. The part that throws me off is when I log back in, I have ~8 random letters filled with random amounts of gold, highest being 1.3k. Maybe a fellow botter trying to remove the future 'competition'? Either way who ever did it wanted me to get banned and didn't think I would fight it. But hey, free gold (5k total) is nice.
Now that is amusing, someone who knows how much gold will trigger a ban is very interesting and shows the person who wanted you banned really wanted you gone. I've seen this before but people weren't getting banned but receiving free gold in their mailbox. Someones definitely trying to remove you as competition, do you make a lot of auctions? Chinese use this method to money launder their gold to sell which is why it triggered a ban.
