I gave this some thought, and concluded that it's best not to do that. Here's why: vBouncer is optimized not to do anything unless a bounced email is found. To implement a hash method, vBouncer will need to run an insert query for every email sent. The hash number will need to be stored in the database for every single thread notification sent. vBulletin will send multiple thread notifications for each new post, relative to the number of members subscribed to that thread, plus an extra qury when a bounced email is received, to match with the hash number sent. This is a huge number of queries, and will defeat the purpose of reducing the server load.

Im much worse about bounced email, if it bounces once they get moved to awaiting email confirmation (and a big red warning appears on every page in that group).

That's why I don't like that option I much prefer to let vBouncer run it's course. Send a warning on the first run, and take action on the second run (defult run period is 7 days).
