I just created this new address in my blockchain.inf/MyWallet - 12LFYVWKz5wWaofhHGnB5EXtkJwGV2yGAy - as you can see it has the word GAy at the end. Can I get the private key for that address and sell it, is that possible.
You can export it but nobody is going to buy it, for at least two reasons:
1 - you know the private key so it's not private anymore
2 - anyone can generate a "gay" address themselves with minimal effort, or hundreds if they wish
3 - why would someone value an address that contains the word "gay" over any other address, or any other word? I could see 8-year-old boys laughing at it for second "look it says gay!", but afterward, you realize that random letters are going to sometimes spell words by coincidence and that this isn't really all that rare or unusual.
