Members: Lock Activation

The Members: Lock Activation filter is to be attached to your own Registration event to force a Member's activated state to be 'no' when a Member is registering for your site. If the Member already exists, using this filter on your event will ensure the Member's activation value cannot be changed. This prevents any DOM hacking to make members activate themselves. If you do not use the Member: Activation field, then you don't this filter on your Registration event.
