yes, I figured it was subscriber based now from your other posts.
The only thing I see as a user is you allow html for posting for that group.
That is really dangerous. Since all it takes is a simple missing tag for html and it breaks the post.
And potentially break the site.
If it were me I would turn off:
Can post using HTML
in permissions
For all but the most trusted users. and then still consider turning it all off for all users.
admins will still have the ability to post in HTML
