You can’t win an argument with a troll like Mendoza Ferrer, and it’s practically impossible to undo the impact of her tweets because you won’t have access to the bulk of her followers.

The only strategy I can think of is to perform a similar search on her messages and background. I know using Milkshake Duck is stooping to Mendoza Ferrer’s level, but given the nature of the Internet Distortion Machine, it may be more ethical than doing nothing or than getting involved in a futile argument (which is in effect the same thing as doing nothing).
