Tip: don’t make it fail completely silently - change this into

```plaintext
if post.nil?
  puts "!!! Could not find post #{id}"
  return nil
end

```

Or you will end up wondering why half your posts is missing and after hours of frustration it turns out to be this.

same for these two

```plaintext
        next if post.nil?
        next if post["deleted"] == "1"

```
