We also restrict sexually explicit language that may lead to solicitation because some audiences within our global community may be sensitive to this type of content

Do not post:

Content that engages in implicit sexual solicitation, which can be identified by offering or asking to engage in a sexual act and/or acts identified by other suggestive elements such as any of the following:
— Vague suggestive statements, such as “looking for a good time tonight”
— Using sexual hints such as mentioning sexual roles, sex positions, fetish scenarios, sexual preference/sexual partner preference, state of arousal, act of sexual intercourse or activity (sexual penetration or self-pleasuring), commonly sexualized areas of the body such as the breasts, groin, or buttocks, state of hygiene of genitalia or buttocks

Content that offers or asks for other adult activities such as:
— Partners who share fetish or sexual interests
