Wikipedia:No paid advocacy

Paid Editing Proposals
In November 2013, there were three main discussions and votes
on paid editing:

No paid advocacy (talk) (closed: opposed)
Paid editing policy proposal (talk) (closed: opposed)
Conflict of interest limit (talk) (closed: opposed)

Paid advocacy is not allowed on Wikipedia. Editors with a financial conflict of interest (such as business owners and public-relations professionals acting on their behalf) must not edit affected articles directly. They may make suggestions on talk pages and noticeboards, and request edits using the {{edit COI}} template, so long as they disclose their conflict of interest.
