The two most glaring abuses, in my mind, were the blackmailing of employees to put their name on a banking industry do-not-hire list if they didn't make sales quotas that proved nearly impossible without the opening of fake accounts. Essentially, WF used the industry fraud blacklist as a punishment for employees unwilling to commit fraud.
The second malevolent practice was using the company ethics line as a kind of honeypot to discredit and fire potential employees who wanted to report opening fake accounts on clients' behalf.
