I've asked this like 100 times already but how isn't he banned yet? That's like 3 warning points alone. Highlighted the racist part. I'm not sure if I want him banned or not because he does give us precious quotes but... he deserves the points.
When you copy the URL and it's longer than what it looks like above, it might not find the 11-character code and leave you with a white box since it can't find the video to embed.
That's why I just copy the code, because that's the only part that goes in between the [ youtube ] tags, like so.
