People routinely use pig farms as retaliation in land use disputes. I saw this case today - basically, a guy fighting with his neighbor hopes to use a pig farm to stop them from doing what he doesn't want.
In another case, you've got a guy who was stopped from doing something, so he threatens to put in a pig farm to bother people.
If the pigs only knew. Not only do we control all aspects of their life cycle so that we can eat them, but we also use them to settle scores with other humans. Releasing wild boar, as one fellow was accused of (but later acquitted), would count too.
