I discovered that there is the tag ecma262, which is the same as ecmascript. So I decided to suggest a synonym.
Round One. I tried to suggest ecmascript as a synonym of ecma262. I got "The suggested tag must exist in the system before suggesting it as a synonym!".
Round four. OK, maybe I don't have any ecma262 score but I could gain it. So I edited added the tag ecma262 to the question Relocating text with js code because my answer has 11 upvotes, and this way gaining 11 ecma262 score. But my ecma262 score was still 0 (see How are tag scores calculated?).
So I have lost 5 rounds and I give up because StackOverflow has totally defeated me.
