Have a look at CBBC's Bullying message board and this is what it says in the introduction:

Bullying

Have you or has anyone you know ever been a victim of racism? Perhaps you've made racist remarks? What do you think schools should do about it? If you heard someone being racist, what would you do? Talk about it on the Bullying message board.

If you're bullied you can put a message on the CBBC on the message board and maybe get help. You might get bullied about being overweight, wear specs etc. But if you're under 15 and bullied about being gay, don't bother posting to the board - they're not interested and your message will not pass the moderators.

The BBC thinks "gay" is a four letter word. And if you want to talk about homophobia or homophobic bullying you can go elsewhere, because you won't get any support from CBBC message boards. CBBC doesn't acknowledge the existence of homophobia, and all talk of it is banned.
