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