GHC Trac spam filter is rejecting new registrations

[Robert Henderson]

Hi,

I've been trying to register a new account on GHC Trac in order to
submit a bug report, and I'm getting the following error:

  Submission rejected as potential spam
  SpamBayes determined spam probability of 90.82%

Could this be a bug or issue with a recent release of the Trac software?
I've noticed people complaining about the same problem on other websites
that use Trac, e.g.:

  https://dev.haiku-os.org/ticket/12947
  https://forum.openwrt.org/viewtopic.php?id=67711

Thanks,

Rob Henderson
