A user wanted to know if they could use dirty jokes or a symbol for the male genitalia made out of ASCII characters as the headline for a Reddit Ad. Reddit Ads staffer /u/MyNameIzKhan was polite in asking the advertiser to keep their ads tasteful, but the reality is that doing such a thing is a violation of Reddit Ads Policy.
The policy stats under Article II, section 6 ‘Obscene, Offensive, or Inappropriate Content’:
Advertisers may not use the Platform to disseminate obscene, offensive, or inappropriate content. Such prohibited content includes content that depicts intolerant or overly contentious political or cultural topics or views, that uses vulgar or sexually explicit words or images, that is designed to evoke visceral reactions, or that is improperly targeted toward minors.
While jokes are clearly fine for Reddit Advertisements or the headlines, writing an ad that incorporates the male genitalia or dirty jokes is prohibited.
