I have image verification on
I require users to accept the email notification
They then go into a moderation queue to be accepted, before posts are seen
I also insist they complete a mandatory profile field (in my case location and the country flag hack). This means the bot cannot usually cope with the mandatory field and/or the hack field and registration fails.
If its a human they usually put a country flag that doesn't match the location - this then gets binned by the admins.
