Okay, I'm trying to make a full list of all the BMF accounts so far. There's black_mold_futures, apparitionist, timecubeevangelist, trumanshow_irl, sealand_macronation, gardenSkink, and now privatized_sun. I know there are others, please comment them if you know so that I can find them later. These posts need to be preserved. Additionally, both myself and another user have independently found what we believe is BMF's reddit account: reddit.com/u/OpenCommune
Edit: ides_of_merch, Bjork_shhh
Edit 2: Another user has pointed out that the account Ketamine_device_tech is BMF-esque and may be the actual original account, but the account was never banned, so I think it might be a different person entirely.
Edit 3: Having read more of Ketamine_device_tech, it actually does seem like a larval-stage BMF. The posts have similar gripes (one post uses the phrase "Jacobin socialists love Walmart), and they use the "amber snacking" emote.
Edit 4: godzilla_vs_jerboa, as pointed out by infuziSporg
Pretty sure this exists from a company called bigme. Might be hard to get in the US though.
