Its pretty illusional and ignorant to ask for people passing an english test before entering the internet. If it comes to gaming and modding russian is a very important language. Large parts of the internet speak spanish, arabic or chinese. If your language is the main language just depends on were you are on the internet.
Also we should not forget that we dont know who we are talking to. The other person might speaks already six asian languages fluently or its might be a twelve year old italian. Give him/her a break.
have also come a long way. They are still bad but if the context is known its now possible to understand arabic or kurdish articles.
And even more importantly this licence already exists. Its called "if people dont understand you they will most likely not talk to you".
Bad French english skills are legendary. Has something to do with the school system, well so ive heard.
