Have you tested it since you added all those mods?

Only the $last command works ...

You are handling vars as arrays and arrays as vars...

Wont delete, or do anything, the IF are never met.

Also when you removed the checks for the steemit / busy you still check if there is a @ and it crashes.

Easy fix:

```
function checkPosts(event) {
var is_post = event.message.content.match(/\/@/gi)
if(is_post === null) {
return;
}```
