Actually. Not interested in paying for an add-on. They moved my post here. Was more asking if there was a way to do it that I was just missing. It would make sense if there was a user filter for filtering by URL or if its even filled in since it can help delete spambots.
I am not aware that Xenforo has an option like that. What you can do though, is to search the database by running a query, and then you can delete all the spammers. But doing that through the database is something that I would not recommend.
