I've sent this using the feedback link, but still no reply or action, so I guess I'll post it here.
I blog in Hindi on my WP.com blog and the comments are also in Hindi 99.99% of times. for some strange reason, Akismet marks all comments as spam & I've to go and unmark them to make them display. I've heard from people using the Akismet plugin that they've had almost 0% false positives, so I'm thinking whether this behavior of Akismet is triggered by non-english comments or what?
an official answer from Matt or someone would be very much appreciated on this!!
