Very interesting and informative article on Quote Posting. Really appreciate that the Mastodon dev team is talking to the community and thinking this through...
"In order to mitigate these issues, we plan to include several features in our implementation:
-You will be able to choose whether your posts can be quoted at all.
-You will be notified when someone quotes you.
-You will be able to withdraw your post from the quoted context at any time."
