Comments broken? Or is it a Spam Issue?

Something crazy seems to going on with comments in general. Are they broken? I'm getting this message when I attempt to comment on my blog:

An error occurred:

Invalid [] range "p-c" in regex; marked by <-- HERE in m/-4-you.info|-com.com|-mobile-phones.org|-site.info|.+cialis.+|.+cn.+|.+diamond.+os.com|.+index.+|.+shemale.com|.+viagra.+|.+xx.+|.a-scuba-school.com|.bg.de|.biz|.blackjack-21.ws|.blackjack-p.com|.blackjack-strategy.ws|.casino-games.co.il|.casino-online-i.com|.casino-royale.ws|.cheapativan.com|.chuanqisf.cn|.cut-jobs.info|.debt-help-bill-consolidation-elimination.com/|.diabetic-care-supplies.com|.gambling-casinos-trx.com|.hbsnwa.org|.imxafterclub.com| at extlib/jayallen/Blacklist.pm line 3098.

What's up?
