UFOX and UFOTwitter hashtags. All other major social media are censoring the topic (including Reddit, which once was supposed to be open). Lately, Twitter started doing so too (it barely suggests ufo topics for me in the last month, even if that’s the only reason I’m there), but the hashtags still work as expected. Unfortunately, on all the fediverse media, the topic is still laughed at (despite the various government admissions in the past year), and so there isn’t any discussion about it. Twitter is where it’s at, for that topic.

Edit: Proving my point, providing a truthful answer to the topic’s question, and still been downvoted by the fediverse en mass.
