The best bits of this were suspiciously the same as a script I submitted to the BBC 'New Talent' competition two years ago. Only my script was much better. Other bits were stolen and used on the Punt and Dennis show. I'm really angry.
And if your script was so good, why didn't they just buy it from you? That is far cheaper than hiring a more experienced writer to steal from you.
People who are nowhere near the industry fail to realize this. It's cheaper for them to just buy your script than to steal it. You are a nobody, you'd sell it for ridiculously cheap and be ecstatic about it.
The only people you need to worry about stealing your ideas are other nobodies that would write it themselves and pitch it themselves, but to who? Nobodies don't usually have pitch meetings set up with anyone important.
So yeah, no. No one stole your ideas that you can't prove you came up with in the first place.
