What do you mean by “some magic happened”?
I did as you said, and got this:
[policy group=testgroup reminder=daily]
Test
[/policy]
Which does not fix the problem. More than a fix, that’s… just not using the plugin.
If I edit the post or rebuild HTML the plugin will work, but the topic will disappear for non-registered users again

It is the same for you from what I can see. In your topic the second post looks like this:
[policy group=trust_level_1 reminder=daily]
We do not use third-party cookies.
[/policy]
So we still have no “solution”. Unless you call solution not using the plugin xD. You might as well have deleted the markup from the second post, same result.
As it is now you can only use it in private categories, so that non registered users can’t see the topic anyway.
