Entitled SEOs tend to be more common than exceptional. While I didn't see anything so hamfisted that it had to be parody, but I can see what you mean.

From the topics on their default page and his other communications, it seems to be sincere.

I read it as a joke by the end but, worryingly, didn't automatically recontextualise it as racist in light of that. Which, I think I agree with you, it is, if it's a joke and all the East Africa stuff is made up for "comedy value".

....? where did the idea of "The East Africa stuff" being made up come from?

Nowhere. It was speculation on my part extrapolated from the premise that the piece was written as a joke and nothing in it could be taken at face value. A little research on the guy suggests I was reading too much into it. Here he is http://www.linkedin.com/in/rishilakhani and his languages are listed as "Hindi, Swahili, Gujarati, Punjabi" - we don't need much more than that to connect the dots.

I thought he was genuinely from Kenya or Ethiopia or somewhere.

I am an Indian born in East Africa ;)

I assure you I am not racist, being an Indian raised in Kenya.
