[Plugin: Bad Behavior] Should I delete the logs?

Hello everybody. I’m using Bad Behavior for about a month or two. Am pretty satisfied with the plugin. But there’re one question bothering me. Bad Behavior automatically block spams and record them and when I looked at the stats the plugin “has blocked 228305 access attempts in the last 7 days”. This is a 2000 pages of logs and 100MB in the database. Will really want to know whether I can delete these logs in the database, or this is something that Bad Behavior record as resource to fight against spams. Thank you very much!!
