I have noticed over the last month that there is /are a number of BOTS who are draining the auction house for popular items (Wildercloth, ore, gems etc) as soon as they appear on the auction house at low price, they are wiped away. I think from the amount that some people are selling at inflated prices shows who these people are and its about time BLIZZARD did something about it. I am on Karazhan and Shadowsong and the chances of buying items as reasonable prices is almost ZERO.
True brother. Id also like to add that people use bots to list all gray items at insane prices and block gold transfer across severs for normal people. Total douches, blizzard please act!
