@garmark93 QOTO has a unique feature, where you can quote the post.. I need to test it but if you use that i thinnk you can CW it.
That said people can filter by hashtag and keywords.. Some people excessively CW but its become unnecessary. My recommendation is to leave CW for things that arent safe for work, spoilers, etc. Leave the filtering to the user to decide.
That said im sure some people might disagree with me here.
