This is something he did over at least two years, including a time when this activity was considered scammy behavior. He was trying to buy at least 10 accounts as part of a single transaction at one point.

I also think it should raise some eyebrows when a number of "sold" accounts have negative ratings removed and/or changed to neutral because of an "internal" resolution. The fact that Lauda leaves negative ratings for sold accounts, account buyers/sellers/etc., means it is at least possible he is either leaving negative ratings for accounts with the intent of buying it at a low price only to later remove the rating, or otherwise leaving negative ratings against his competition. Similar things can be said about his SMAS list. Neither Lauda's removed trust ratings, nor the SMAS list is particularly transparent, and both seem to use an arbitrary criteria.
