A core aspect of ingress is interfaction rivalry, as such friendly banter can be expected in all comms. However, never forget that if you start talking shit, players will reply in the same manner.

To add to this, all players can and will troll, trash talk, or generally stir the other team via chat. However, despite this, if this comes up in X-faction chat the appropriate response is to decry such boorish behaviour and to state one's superior morality that they do not engage in such behaviour (but they do).
InterfAction, no R. Friendly, too...sorry, grammar hound.
Thanks for that @IIIIIllllIIIll. I've fixed that up. All content on the site is submitted by players and often using a mobile device. If you are interested, we are looking for someone to help in the process of editing all the rules to make them consistent and a little bit more enjoyable to read. If you are, email me: caffeine at ingress.buzz.
