The cypherpunks account can no longer create or even reply to tickets. Not sure if something else broke while someone tried to work on this...
The obvious workaround is to use this account (cypherpunks3) with the same password as the original cypherpunks account. Or, if this behavior is deliberate, someone should update the main page to report that the cypherpunks account has been disabled (due to abuse?).
Doesn't much matter what you're okay with, because the admins don't seem to be okay with it. teor said right there that the spammer can already solve captchas.
The current captcha isn't a captcha, it's a joke of a captcha, with a relatively real captcha like the Google ones I think it should be ok. Also we haven't seen such a breakdown on cypherpunks here on trac since '92.
Google reCAPTCHA may not be desirable for privacy reasons, but in general is it feasible to change what kind of captcha is in use, or improve it, in a way that doesn't use third-party servers?
