Spamming small groups of friends via text or social media groups with annoying news headlines from unreliable sources. Following up with strong calls to take actions. Slinging mud and engaging in personal attacks when asked to cease and desist.
Quit jeffing me already! You've that stupid YouTube video link 100 times already and nobody cares. You're not going to save the world by posting spam to your friends followed by insults.
