Boulder Dash Forum

Last times, a lot of spam has been posted here. For me quite annyoing as I often need to clean up threads and user accounts from the forum.

It looks like the same person/bot is registrating every time with another username. I don't know how they pass the screen with Anitspam question, but if this continues to happen as frequently as now, I will need to block the registration for new members... Anyone has other ideas?

The "anti spam question" lacks any randomness, which makes it very easy to code a bot registering new accounts automatically all the time.
Maybe add some quiz which a casual BD player can answer. Do the actual question in pictures which can't be read easily by OTR software.

Thanks!
I've changed the question, let's see if this helps for the short term.
