Irritating spam

Visited one of the boards that I check once in a while and saw a lot of spam there. It made me really sad. I mean if you own a board which has a topic you love then how comes you don’t find time to delete spam and spamming users?
And yes I know how boring and time-consuming it can be because I have a board myself that doesn’t use image confirmation. It get’s a post maybe in couple of weeks but several fake users a week :(.
