Who is Grok Testuser?

[Katie]

Can someone tell me who or what Grok Testuser is here on Goodreads? He/She is reading one of my books at the moment. He/she is reading 16 other books as well. They have lots of friends, all of whom are called Grok Testuser and all of whom joined Goodreads in October 2013. Some sort of Goodreads robot? What does it do? I noticed one of the ratings on that book vanished overnight and my average went up by 0.4 as a result, so I'm wondering if it (sorry, he/she) is clearing out false accounts?

I have one of them reading my book as well. Nothing untoward has happened so I suppose I'll just have to wait and see what happens.

Saw something on Twitter about this user...reply looked like it was from Goodreads (that's an assumption). :)

Basically, said it was a test user for Goodreads but no other explanation. A couple of my books have this user as reading it. Wonder what they're doing?

Thanks for that info, Shereen. I now have two Grok Testusers reading one of my books and another Grok Testuser reading another. Should I feel honoured or worried, I wonder?

Ah that explains it. He/she/it was reading both of mine, sometimes twice. Lol.
