38 * Plugin to check submitted notices with blogspam.net
40 * When new notices are saved, we check their text with blogspam.net (or
41 * a compatible service).
43 * Blogspam.net is supposed to catch blog comment spam, and I found that
44 * some of its tests (min/max size, bayesian match) gave a lot of false positives.
45 * So, I've turned those tests off by default. This may not get as many
46 * hits, but it's better than nothing.
