What are these nonsense paragraphs in Stephen Baxter's Weaver?

"I'm sorry for the bad quality. However we really did as what you said. To make things clear, could you please give me name of jobs with bad quality? If possible, the errors with picture. Only told us what's problem is no enough, The more pictures you can send to us, the more clearly we can understand what's the problem.What are you going to do, Dad, thump me again?'"

This shows up in Weaver at the beginning of Part 3.

I wasn't able to make sense of why this shows up several times, apparently seperated from the story. I get the feeling it's an indication of wobbles in the timestream, but I don't see any other references to it in the book.
