An Xbot is someone who defends the Xbox brand based on actual facts presented to the discussion. Most "xbots" are usually fans of the Xbox gaming system. Xbot is only a term used by a "sony
pony" (see urban
dictionary for a indef detail of a sony
pony) because they refuse to accept anyone defending Xbox. There are various unbiased
people (usually YouTubers or some various gaming journalists) that only report on news. If the news is positive for Xbox in anyway, then Sony fans will usually call them "xbot". Being called an Xbot is not a negative thing. If you're called an Xbot, it means you've presented something factual and a Sony fan is upset that you gave Xbox a positive light.
