I empathize with your situation (recluse, issues, etc.) I lose much of my sympathy to your cause with your all CAPS demanding a clan leader, WG, or anyone else answer at your perceived beck and call.
You demand a response from Wargaming, and while it appears warranted, the frank fact of the matter is you put yourself out there to be baited with a demanding tone and what many would concur are excessive demands.
At the end of the day, there are folks on this forum and in game who are friendly, personable and genuinely helpful to players who seek support. At the other end of the spectrum are those who will pull out all the stops to drive one mad and are truly cruel.
That said, if you are the introvert/recluse you claim to be, try to keep the hyperbolic demands down. Have a question? Ask away, but think for a moment before you click post how that message will be received by the reader. Without seeing your face/body language, without hearing the tone of your voice, all people have to go on is what they read. All caps is considered yelling (whether you think it is or not), and emails/posts are sometimes read (and message received) that isn't what you intended.
As for in game play- simple. Go to SETTINGS. Click the GAME tab, and under CHAT select both "Allow messages from Contacts only" and "Censor messages". WG put those two features in the game for just this reason.
Best of luck, and I hope to see ya out there.
