Explanation

Warchalking (D) is the practice of drawing chalk symbols on sidewalks, walls, or other public surfaces to indicate the presence and type of a nearby wireless network - including open networks available for free use. The symbols originated from hobo code traditions and were popularized in the early 2000s.

Why the distractors are wrong:

• Spamming (A) refers to sending unsolicited bulk messages, not physical network indicators.
• War driving (B) involves driving around with a device to detect and map wireless networks - it's about finding networks, not advertising them.
• War dialing (C) is an older technique of automatically scanning phone numbers to find modem connections, predating Wi-Fi entirely.

Memory tip: Think of the "chalk" in warchalking - it's literally about drawing (chalking) symbols in public, just like hobos once marked locations with chalk symbols to share information. The "war" prefix ties it to the same family as war driving/dialing.
