Just three rules to prevent an advertisement battle:
1. Every candidate can have only one self-presentation post. All questions and replies to that particular candidate must be posted as comments to that post. Use the search function if the post has gotten buried. If you want to ask a question to all candidates, you can (and should) start a separate post of course.
2. very candidate can bump their self-presentation post (bump = move the post to the top of the page by making an unnecessary comment) exactly ONCE during the election period.
3. DiEM25's social media pages (those with a logo instead of a personal picture) shall remain neutral in the election and not encourage people to vote for anyone, as then candidates who have access to post on DiEM25's pages would have an unfair advantage.
The same rules apply for DiEM25's Facebook group
