Tabletop.social has been update and is now running Mastodon 4.5.0.
That means that we have "Quote toot" enabled.
Sadly they also come enabled by default, and you would need to disable it yourself if you want to avoid people using it without your consent.
Head to the Preferences -> "Posting defaults".
The 2nd drop down "Who can quote" then can to be set to "Just me".
❗ Don't forget to hit the save button at the top of the page for the change top take effect.
You can quote this toot.
