Sumbuddy thinks I'm dumb

I  just got one of those spammy emails with the link to an intelligence test.  The body of the email said "Someone thinks you're dumb!  Thier score was 127!  What's yours?  Click here [link]"

I suppose it's too much to hope for that the use of the plural possessive pronoun (spelled incorrectly) when referring to a single person was an intentional, tongue in cheek joke.
