Maybe there should be implemented a limit of feedbacks / trust / flags in a given time (if it doesn't exist already)?
There are limits already, but they are quite high:
OK, new limits:
- You can't give more than 5 ratings to a single user.
- Your total sent ratings is limited to three times your activity, but at least 1.
- The comment length is limited to 600 characters, but each newline counts as 120 characters.
