Hello,

it's possible to remove all accounts flagged as spammer? Also all blocked accounts? If yes - how?

So you want to mass delete all spammers/blocked accounts.

This is not built-in in IPB since there would be no advantage from deleting all these members.
What is the reason you do want to do this?

I checked the IPB code to see what IPB actually does to "Delete" these members when you click the delete button from the ACP

It calls "$member->delete()"; which calls "hideOrDeleteAllContent(true)" and a bunch of other stuff..

The easiest thing to do as I can see you have coding experience with IPB, is to write a script that gets all banned/spammers and then call ->delete() on it
 

I know all this stuff about writing a code. But thanks for the answer!

Hoping someone skilled writes a plugin for this. My reasons are my reasons  

we inherited Admin on a site where anyone who caused bother in the past has been marked as a spammer instead of banned / suspended. Is there any way to bulk delete these please so we can start from scratch?
