We had several attacks in Bern as well (quite some time ago, actually). 
We just do not allow uploads, which seems to be enough to scare most of 
them away. Of course, this does not disallow them to put links, and you 
might need uploads, but if you can do without uploads you can give it a 
try...

PS: Yes, you can of course set the passwords, but I tend to always 
forget the ones I really need so just disabling uploads is easier :-)
