I figured as much based on your first tag. You can't delete posts on the blockchain, only edit. If you want to clean it up, maybe just do a one liner to say why you've had to delete the original content, and add one of your nice travel images so at least people have something to look at. It's much better than to have an empty post as it looks very dodgy.

Getting your content to the right audience is the most important thing on Hive and that's why the communities were created. Engagement is another thing. If you get those two things right, your half way there already.
