Why we need a hide button?

I have been trying for long to delete an unwanted post but to no avail. But then i learned that its on a blockchain and it won't disappear.

So what's the solution?
I would say we need to have a hide button where any user can hide the unwanted post on their blog. Anybody visiting someones blog wont see posts that are irrelevant.

How can you make that happen?
All you need to do is vote for it and lets the world see what the community want. Together lets do it to have a hide button.
