The spam is on bug 19367. I can imagine the same people posting on many different bugs: https://savannah.gnu.org/bugs/index.php?19467 I've just flagged all the comments as spam: > Clearly the captcha is insufficient to prevent spammers from signing up, > but I've already said everything on that subject I can think of. I would imagine signing up might be done manually, but a bot then goes to hundreds (thousands?) of bugs and posts comments. > In my (short) experience, few helpful comments have hyperlinks to > external documents - > > Disagree.

What about a dedicated captcha for when the post contains a hyperlink or is in "rich text"? I've seen a site have a captcha if there is a link to the outside (so links to internal documentation or other bugs don't trigger it). If external links are commonly used in real bug reports, I don't know how else to stop the spam. Jan
