I'm not aware of legal definitions but to me that sounds like stalking. Friendly contact would be an email or a phone call or talking to them at a public event but not setting up a team of field agents to follow someone and track their habits, then threaten with legal action at their door. From https://en.wikipedia.org/wiki/Stalking https://en.wikipedia.org/wiki/Stalking: > Stalking is unwanted and/or repeated surveillance by an individual or group toward another person. Stalking behaviors are interrelated to harassment and intimidation and may include following the victim in person or monitoring them. > According to a 2002 report by the U.S. National Center for Victims of Crime, "virtually any unwanted contact between two people that directly or indirectly communicates a threat or places the victim in fear can be considered stalking", although in practice the legal standard is usually somewhat stricter.
