When I click on my "Refer a Host" link the page comes up but instead of saying "You're Invited By Luke" (me) it says "You're Invited By Shrinith" (not me)
I don't know who that is.
I also noticed it says "invalid code" in the address bar.
Make sure you report it to Customer Services as that's not right.
You may also like to use the @Shrinith name search in here and see if anyone comes up with that name, or in Google with the related keywords to their listing.
You may also like to use related Keywords in the Searchbox here in CC to see if anyone else may have had similar issues arise.
