Hoping someone in authority happens to read this. Tried to report it to the correct address, but their captcha image script is broken (Irony).
Says something about validation and bots, but doesn't say _WHY_ the post was blocked or what should be done differently. There is no captcha field that I can see or any other apparent way to avoid this failure.
-- That's funny.. Lame captcha's.
Sorry about that. I'll fix it up.
-- Okay, it's fixed now... The Captcha works too.
The way the new protection works is a bit of a hidden protection using HMAC on a key sent back and forth, challenge response style. This kills about 95% of the bots and only, so far, broke the upload script. My apologies.
