One can use a zero-width space (using something like
​in their HTML) between the @ and a twitter user name on the original post and the syndicated copy will not have the traditional @mention link or notification functionality.
Here’s an example
- Original post: https://boffosocko.com/2020/09/17/55777062/
- Syndicated copy: https://twitter.com/ChrisAldrich/status/1306748549233815553
This reply can also serve as a test for the functionality within Github where I’ll “tag” both @kylewm and @snarfed, but if it works, Ryan shouldn’t be auto-linked or notified.
