Hi

FWIW,  I have deleted well over a dozen accounts and hundred questions in the last few days and several new user accounts even after this mail was posted.  It is likely a single persistent spammer and perhaps scripted.   Some serious measures are needed at this point since some of us constantly deleting users accounts and postings just isn't scalable.

Possible options

* Block by IP address
* Limit open id signs to just Fedora accounts
* https://pypi.python.org/pypi/stopforumspam/
