On world seed 1, creepers spawn like its their day job. There are way too many creepers. Creepers should be banned. Creepers are awful. I was evicted from my house by a pair of creepers. Creepers destroy our homes and kill our pets. Creepers are only good for gunpowder, and only when they are IN FRONT of you. Being killed by a surprise creeper during the day is the worst!
It's a coding bug... not a spy.
