We already have a question discussing how to address answers that are advocating a violent approach. One of the top answers there however, suggests:
Maybe when we have a larger body of examples we'll start to see a pattern that leads to a policy discussion, but I recommend against trying to shut down anything that smells of violence now.
I think the time is come to have such a discussion. Lately, we've had a question where 2 answers were suggesting some form of threats of violence or harassment: this (now edited and locked to remove the threat) and this one (now deleted by the community, offering as one of the options to make her stop out of fear of having to pay damages or to harass her about how evil she is as a person for feeding the dogs unhealthy food).
Both attracted a fair share of custom moderator flags asking the moderators to delete the answers since they're advocating violence/harassment (especially if we were to follow IPS custom and ask for those writers to explain exactly how to do this and provide some back-up as to what worked), and even some rude/abusive flags. Yet, since the question I linked above seems to still suggest that we're okay with such answers, I am unsure how to handle these flags.
Please take your time to read through that other post, see what was already said and if you still agree with it when applied to these two answers.
Some other interesting stuff you might want to look at for making an informed decision:
this Meta SE post on questions promoting violence. I personally couldn't find anything on answers, this may be due to such answers not being very common on more technical sites.
The definition of Interpersonal Skills, as given by Google:
the ability to communicate or interact well with other people.
A more scientific definition of Interpersonal Skills, as given by International Review of Industrial and Organizational Psychology 2006 , chapter 3., that I often encounter when looking at more scientific articles:
Interpersonal Skills are goal-directed behaviors, including communication and relationship-building competencies, employed in interpersonal interaction episodes characterized by complex perceptual and cognitive processes, dynamic verbal and nonverbal interaction exchanges, diverse roles, motivations and expectancies.
This question about whether or not we'd allow questions on pick up artistry. We specifically banned it because it isn't about interacting well and violates be nice.
Should IPS continue allowing answers that advocate violence/harassment?
If so, do we hold this to the same standards as other answers, do we want to know exactly how to do it?
