Good idea, but it will most likely not be available on the first version of the new board when we go to it. There are more options on the new board for ignoring people, but they mainly have to do with new "Private Topic" fuctionality (like PMs you share with more than one person). Here is what the new board will offer:
Adding users to your 'ignore list'
To add another user to your 'ignore list': click on their username, then on Manage Ignores. This takes you to a page that lists their user ID/Name and has a space for you to add an Optional Reason to briefly explain why you're ignoring this person. This field is optional, but if many people are ignoring this user with the same reasons, the site administrators will see this and will determine if other actions are needed on their part.
This page also allows you to set the Ignore Level:
* Level 1: Tinted Glass (Placing users behind the 'tinted glass' will prevent them from inviting you to a private topic.)
* Level 2: Wood Crate (Placing users in a 'wood crate' as the same affect as 'tinted glass' plus they will not be able to view your profile.)
* Level 3: Lead Box (Placing highly toxic users in a 'lead box' has the same affect as 'wood crate' plus the user's topics and posts will be hidden from your view. Their names will also not be displayed in the 'online' information.)
