Clarification on the rules/etiquette of Competitive play.

I'm just seeking clarification on an issue that annoyed me. I was playing a cw, i was france my opponent was uk. Turn 1 i circle walled my cap with 8 units with the intention to wall inside it turn 2 thus keeping my capital safe until turn 4. Overall taking 11 units.

after the turn ended i found the circle wall had been wf'd. the wall looked roughly as shown in the following screenshot and the red circle was the location of the wf, on french territory.



As we all know you are not meant to place units on your opponents territory turn 1. Or interfere with walls on their territory. Sometimes this is unavoidable in cases where countries are almost on top of each other. However the standard etiquette is usually to pretend that the walls are there and continue as normal.

When the wf happened to me in the cw i just thought whatever and played on. He probably will pretend the wall is there. Next turn i found a wf beside my cap breaking the inner wall i had made within the circlewall. I was pissed but i finished the cw. After however i criticised the other player for his rulebreak only to be laughed at and told to stop making up rules. Am i wrong in what i thought was always the standard? Is it ok to interfere with walls on another persons terrirtory and then pretend theyre not there? Should we applaud the other player for not capping me?



his argument was that the wf was on belgium and not france, it was on france's boarder and there are witnesses but whether he is right or wrong about the wfs location he still interfered with the wall on my territory.

Feel free to give your opinions, and if anyone knows where the rules about turn 1 territory invasion and wfs is stated, please post it. Or is it just an unofficial etiquette/standard some of us maintain?
