Rules of Posting

July 2, 2024

You will have read our site Terms and Conditions that you agreed to when you signed up to PistonHeads, but here are the important bits with regards to posting in the forums.

If you are a dealer advertising with us, you should also read our Guidelines for Dealer Pricing and Marketing on PistonHeads, which set out the additional rules you will need to follow in your adverts.

Our approach to moderation

PistonHeads is first and foremost a motoring forum. If our team feel that you are not here to primarily discuss motoring or your posts are not in keeping with the spirit of PistonHeads, we may suspend or ban your account.

We restrict new member access to certain forums for a period of 14 days; once that time has passed access will automatically be granted. As we are primarily a motoring forum, posting rights to our News, Politics & Economics forum are granted after one year of membership and a minimum of 1,000 posts. We also apply a rate limit to the frequency with which you can post, and AI tools to assess content of new posters, to help combat spam.

Swearing is not in itself prohibited (although abusing other users or our moderators is). We do however use automated tools to detect and redact certain swearwords in your posts automatically.

With thousands of posts every day, we cannot proactively moderate every individual post. However, our moderators do proactively monitor overall trends, and if they identify a significant outbreak of a particular kind of banned content or problems with banned users getting back in, they will proactively go looking for posts with that content or by that user.

How to report, how to complain, and how to contact us

If you see any material on our website that you would like to alert us to or if you feel you need moderator assistance, please use the "report" button in the top right of each post. We will be alerted and will take appropriate action in line with our rules referred to below.

If you have been subject to a moderation decision that you believe to be inconsistent with these rules, then you can raise a complaint according to the complaints procedure set out in our site Terms and Conditions.

If you have any other forum query, please read our FAQs first before contacting us. If you still need help, please contact PistonHeads through
