From now on, you can message #anonymously on @wpn with a disposable account.
Sign up at `anon.woodpeckersnest.space` with #gajim or #dino. I only have #conversations on my phone and I don't think anon login is available there.. let me know if any other Android/iOS client works for you.

To be noted: S2S connections are denied for anon accounts, for good reason - It's not like I want my server to become a spammers' heaven.

To be noted²: I'm testing, everything might change.
