I am programming a Twitter post to post once a day pre-written tweets. I currently don't know how to prevent it from posting on Shabbat. Is a twitter bot posting on Shabbat permitted?
See this article by R. Gil Student which discusses this and other related issues.
Possible problems involve:
- Using a timer to perform work on shabbat
- Marit ayin - giving the appearance of doing work on shabbat
- Running a business on shabbat (where applicable)
However, to quote his tentative conclusion:
My initial reaction is that scheduling blog posts, Tweets, e-mails, etc. should only be done if it is for personal rather than business use and should include a disclaimer stating that it was scheduled before Shabbos.
