To whom it may concern :)) ... i hereby declare that i am the one who wrote on bu.noblogs.org and who now writes on https://biebabebi.tracciabi.li/
I can prove the second assertion: just see my bio here, https://todon.nl/@junes, where the link to biebabebi.tracciabi.li is verified (https://docs.joinmastodon.org/user/profile/#verification)
I can somewhat prove the first assertion too: before autistici/inventati was shut down, the link was to bu.noblogs.org, it was verified, and maybe some people here does remember this and would testify :))
