Thanks Ric, yeah we have a good system on here and I have also been literally spending an hour or two each night blocking IP's for the last month or two which is starting to wear me down to be honest...lol

I haven't blocked smaller prefixes though, I should start to try that but the first few prefixes are so scattered I reckon they are using proxy. We did this a while back and I blocked entire ranges which resulted in a lot of genuine countries, including some Aussie members not being able to access the forum.

I'll try out a much larger range and see how we go.
