I think you could trigger popup with custom JS snippet added in `/admin/customize/css_html`.

For example, if your category name is _nsfw_, try something along this lines (when `document` is ready):

```javascript
  if ($('#topic-title a.badge-category:contains("nsfw")').length) { 
   console.log('This post belongs to NSFW category'); 
  }

```
