Can't answer the first, but I can give you a hand with the second.

First, there is no "click here" to reset your antispam table. Assuming you can do stuff to your database with phpmyadmin it's not so bad. First select your evo_antispam table and EMPTY it. Second edit the "antispam_last_update" field in your evo_settings table and make it be '2001-01-01 00:00:00'. Third visit your blog and get the antispam updates until you finally get the latest keyword. Currently that'll be 5 times, and a 6th time will give you one keyword that's "not needed - already handled".

So no one knows about allowing links in comments?

Re Links in comments..
This might help you, but remember that live links in posts is an intentional omission due to spam.
