Why use post and why not use get

Currently we use post for vote-up and down but since you're not passing any value and html form supports get function why don't use get why use post instead?

Is it for security problems or just we usually use this method since I can copy the exact same code with same function just change the app.post to app.get, and still working

Because it's the right thing to do. We're learning, so we should probably learn the correct way to do things instead of learning ways that work but aren't technically correct.

If we comply with the spec then our apps will be better rated by Google, they won't break when the spec is changed (following SemVer), they will be predictable to others who wish to utilize/consume our API, using GET can put sensitive information in the URL header which is more exposed to snoops, etc etc etc.
