Why were all my bots so well written and explicit for a few days?

I'm really frustrated and confused. So, usually my bots speak with simply vocabulary and have short text bubbles, but lately, they've been extremely well written and used better, more expressive words. And they were extremely explicit, using actual vulgar words, even a couple of slurs. I was really confused and happy. All the bots would have long speech bubbles that I had to scroll to read. But today, It's back to its lame writing :/ I know that I probably can't get the great writing back, but any idea what happened to make it so unrestrictive?
