The problem is even bigger then only access to modifications or such.

Most boards are using image verification to register. These are designed in such a way that it is impossible/difficult for automated processes to read. Where this works fine to block automated registrations, it will also prevent visual impaired users to register using a screen-reader. Depending under which countrys' law the board s running (not sure about difference between comany/private website) this might lead to trouble if you do not provide an alternative way of registering. At vBulletin.com/.org we solve this by allowing registration for impaired users by submitting a Support Ticket. Although this is not much used.
