To piggyback on this, I used to play Counter-Strike 1.5 (and later 1.6) a lot. There were servers that ran scripts to automatically chuck people into the air and deal them damage (often called a slap) if they didn't change coordinates on the map for too long. Some would just auto-kick players for doing so. The anti-camper hate was common.

The server I frequented was far more lenient, but camping that prolonged the round(since dead players could only watch, and the rounds were 5 minutes long to make walking and crouching more viable) was generally frowned upon if they weren't outnumbered or defending an objective.
