Hi, 

Question: How do I remove one person's posts after deleting his account? On the forum it now states 'Guest Nickname' after an account was banned and then removed.

How do I delete all the posts marked like this?

You need to delete the content before deleting the account. Once deleted, there is no user anymore. The posts are just guests posts. So you can’t easily access a specific user’s posts anymore from the ACP or the front end. 

Okay. Thats crap, cause someone deleted the account already. Is there a way to delete al 'Guest' content?

Is see now that there is an option in Spam Prevention. But, that keeps getting a 504 time out... Could that be because it are over 10k posts? Should I keep on using it, meaning: does it work in the background despite the 504 gateway timeout?
