logintoboggan and autoassign. Assign after confirmation.

I have my registration process set so that users can set their own password upon registration and log in upon form submission, but are in an 'awaiting confirmation' role set by loggintoboggan that has no privileges to post content until they are assigned a 'member' role. That's where I need auto assign to come in. Currently however, it assigns the role to the account immediately, regardless of whether the confirmation link has been used, defeating the purpose of the confirmation process and allowing spam bots to post content.

I saw an ancient thread on this for 5.x but its two years old and I have no idea what to make of the 'solutions' they link to, which looks like they required you to poke around inside the modules code anyway, or if they would even apply to my 6.x site.

Would it be possible to have the option to have auto assign wait until the user has clicked the link in the confirmation email sent after registering an account before assigning roles?

Thanks for reading.
