Any attempts to fool the language filter will not be tolerated. I don't care if you're doing it while helping a friend or not.
I'm glad to see that things have been patched up here, but there is no reason for such drama on our forums. This is a place for discussing games and related topics, not for dealing with personal matters or for piling on humiliation or for participating in pointless name-calling. Many online arguments can be attributed to people misinterpreting someone's writing, due to the lack of vocal inflection or social context. People also tend to be more blunt in their criticism when writing online; it follows that you should also be more resilient to what people say about you.
In any case, if you feel that someone has personally insulted you, report it to the moderators. No one, not the insult's recipient nor the other people following the thread, should respond to an insult.
