There only needs to be one report per violation, anymore is extraneous as we will always review the topic in full.
If you feel something is urgent and needs immediate attention (think: porn, phishing links), you can message a Moderator for that section.
If there is just spam or flame posts, just your single report for the violating post(s) is sufficient.
A Moderator for that section will review your report as soon as possible. Multiple reports doesn't change response time.
Feel free to PM me if you have any questions about the reporting process.
