How to delete posts by a spammer

My forum got attacked by a spammer, how can I bulk delete all the posts
I banned the IP address and the email address but the forum is full of posts from the spammer.

Hello,

There is no way in the admin panel to automatically delete all posts made by a member. You will have to go through each post and delete them one by one.

However, there is a tutorial on the French forum located here that adds a feature which deletes all the messages of a member.

Thanks for letting me know there is no option and maybe it is something Forumotion can work on.
I've deleted all the posts the hard way.
You can close this and thankyou.
