Yeah, I think the opt-in nature of it is really important. For the record, I appreciate beyond measure when people on my flist cut and label fandom-related negativity and venting; it gives me the option of deciding whether or not I am in a headspace to engage with it. Tumblr tagging can serve the same purpose, if people use it. Discord ... is just a lost cause. XD I mean, I enjoy Discord, but there is literally no way to prevent seeing certain kinds of content unless it's walled off in specific forums and the mod actually enforces that.
