Is this a bug or something specific to our installation? It's really proving to be problematic!

Please could you provide some examples I can take a look at? If they are posting and you have posting disabled, either your settings are out, or there is an issue somewhere. 

@LiamH - just checked your site as a guest; there are several forums open to allow guests to post new topics.

I suggest you look at the permissions that the Guest group has for forums:

You also have "Post before registering" enabled:

To clarify, there are indeed areas with those permissions to post. However they appear to be in a technical support area, so not sure if thats intentional on those. If its not, I would need an example

Hey Marc, we did allow guests to post in technical support but nowhere else. We are getting roughly 1-2 posts from Guests each day. I will DM you a URL to an example of a post.

Turn off "Post before registering"

We want to keep the post before registering but only for 2 forums which it's enabled in. We don't allow guest accounts the permission to post in the other forums, but somehow we are recently getting exactly that.

It's designed to allow them...they can "Post before registering" as your members group has permissions to do so...

This is happening when people post on your site as a guest, using post before register. You actually shouldnt be able to see that post unless they do register, but they are showing on your site. This is very likely the result of one of your 3rd party applications. I would advise on disabling all of those, then trying to do a new topic while logged out in the same section, then logging in as yourself to see if you can see it. You shouldnt be able to

Thanks for this.  I just came here after realizing spammy guests were able to post junk.   I had no idea this was set to ON

This wouldn't allow Guests to post, they would still have to register 😉
