What is the valid way to mitigate users spamming many rooms at once? Surely redaction alone isn't enough

Do more rooms need captcha to join by default?

Captchas are annoying and an accessibility hazard but...?

Hello I have companies in US and can accept bank transfers daniel90@xmpp.jp

xmpp.jp operator here? Seems Daniel is spamming from there?

yep, today it's xmpp.jp

jonas’: spam is coming from xmpp:daniel1@chat.sum7.eu

kikuchiyo: I think genofire already banned that ine

> What is the valid way to mitigate users spamming many rooms at once? Surely redaction alone isn't enough Fuzzy DCC would be a good start.

kikuchiyo: what's that

moparisthebest Distributed Checksum Clearinghouses https://www.rhyolite.com/dcc/

Also this could be evolved https://xmpp.org/extensions/xep-0377.html

That's actually very interesting

When I read DCC I immediately think of the bad old days lol https://en.wikipedia.org/wiki/Direct_Client-to-Client

IIRC that was pretty much the approach taken by Vipul's Razor (and then Pyzor and some others) for e-mail spam management?

So to reframe the past in terms of more modern pop-culture..., "it's sort of like bitcoin except negative (where the blockchain stores demerits instead of credits)".

kikuchiyo: setting up a central server to handle reporting and checking is easy, though probably a privacy nightmare, but how do you handle... Moderation?

Like I don't like you so I report everything you say as spam, that kind of thing
