The license permits Substack to alter and reproduce user Posts—not merely display them—which means Substack can change the form or presentation of user content as part of platform operations.
Interpretive note: The phrase 'otherwise act with respect to your Posts' is broad and its full scope is not defined in this excerpt. The canonical claim reproduces the language without interpreting that phrase beyond what is stated.
The updated terms establish new content moderation procedures, including use of automated detection tools (hash-matching for CSAM, keyword filtering, direct message scanning) followed by human review before enforcement action, except where immediate action is necessary to prevent serious harm. Substack will notify users when content is removed or accounts are suspended for policy or safety reasons, unless notification would compromise an investigation or risk harm. Users may appeal content removal or account restrictions by contacting tos@substackinc.com, with Substack committing to respond within 3 business days. Beginning December 1, 2026, local VAT, GST, sales, or use tax will be added to Paid Subscription purchase prices, collected by Substack and remitted to applicable taxing authorities where its service provider is able to do so. You can report content violations using the report tool on each post or profile page, and appeal content moderation decisions by contacting the support email address.
