Wow, that looks like it's meant to cause trouble for anyone checking SPF.
I guess that will be a good test case to see how various implementations
handle it.

Does CLASSMATE.COM have a redundant SPF record?:

D:\p32\socket\iftp\release>spf mail.classmates.com
"v=spf1 mx ptr include:classmates.com -all"
Whats the point here?
I suspect they did it by accident.
I have identified multiple hosts who do this accidentally either the
result of a language barrier or simply not spending enough time reading
and understanding. I'm not quite sure what would lead someone to go and
include their own host, or a host that then recurses until the limit
(hopefully its employed I know both libSPF and libspf-alt do) is reached
and the parse is aborted.
Nixtra whom I spoke back and forth with over the course of a week has
fixed their record. It in this case came down to I believe a
combination of language and not enough reading.

This impresses upon me that we might wish to explore additional (if any
exists already) translation of relevant materials to help prevent this
from happening.
I have not quite yet revealed DDT to the public yet, but it is currently
contacting postmaster(_at_)domain automatically when it finds severely broken
records. We'll see if this helps.
Cheers,
James
