Vote manipulation is against the Reddit rules, whether it is manual, programmatic, or otherwise. Some common forms of vote cheating are:
- Using multiple accounts, voting services, or any other software to increase or decrease vote scores.
- Asking people to vote up or down certain posts, either on Reddit itself or through social networks, messaging, etc. for personal gain.
- Forming or joining a group that votes together, either on a specific post, a user's posts, posts from a domain, etc.
Cheating or attempting to manipulate voting will result in your account being banned. Don't do it.
