the forum rules here do prohibit members from sharing their referral codes (as I am sure everyone has read the rules fully, right?)
21. Competing Sites, Businesses, Individuals and Organizations You agree not to attempt to gain traffic from M3OC in any way, including but not limited to, links in posts, signatures, profile information, PM's, or emails. This applies to, but is not limited to competing sites, businesses, individuals or organizations. The embedding of Tesla Referral codes in posts or signatures is not permitted. You accept that M3OC has the right to erase any information displayed/posted on Model3OwnersClub.com that may push traffic towards competitors.
if you use social media, have a youtube channel, talk to people, etc - you can get your referral code out any of those ways.
