vBulletin 4 Request - Block Opera Mini

[Outlaw Mantis]

Opera Mini has been a problem for me. Though it is sometimes used by spammers, from time to time I use services like Postloop. There are some people who create multiple accounts which breaks the TOS, but they use the proxy features of Opera Mini to hide their identity. There is an online demo of the browser (uses Java I think), so they might use Opera Mini on their desktop so they can more easily exploit sites like Postloop.

I hear this should be an easy case of user agent blocking. I've given a couple of scripts a try as plugins but I can't seem to get it working. Ideally I'd like a block to redirect the Opera Mini user to a page explaining the block.

If anyone can make such a mod I'd be very thankful!
