Community Guidelines is the NOT "TOS" (Terms of Service Agreement). They are just sugestions. In fact, it SPECIFICALLY indicates to the "COMMUNITY FORUMS" here..."The OfferUp team may reach out and may remove content from the OfferUp community forums that violates these guidelines."....rather than to the ACTUAL POSTINGS.
Exchanging phone numbers is NOT prohibited in the TOS and within the guideliness in relation to the ads. Now, if you include your phone number within an image of the post and/or within your profile <<<< this act can be a bannable offense (read the TOS).
BTW, Let's be logical and honest..."safety" has NOTHING to do with the reason as to why OF does not want users to communicate outside of their messaging system. Anyone can sign-up with a "throw-away" email address and communicate in the same manner as the OF messaging system.
HINT: It is the SAME EXACT REASON WHY eBay used to prohibit including phone numbers within an ad.
