Please. Captcha by default. Email domain filters. Auto-block federation from servers that don't respect. By default. Urgent.
And yes, to refute some comments, this publication is being upvoted by bots. A single computer was needed, not "thousands of dollars" spent.
Sigh....
All of those ideas are bad.
I am not saying captchas are completely useless, they do block the lowest hanging fruit currently. That- being most of the script kiddies.
Issue number one, has already been covered below/above by others. You can use a single gmail account, to basically register an unlimited number of accounts.
Issue number two. Spammers LOVE to use office 365 for spamming. Most of the spam I find, actually comes from *.onmicrosoft.com inboxes. its quick for them to spin it up on a trial, and by the time the trial is over, they have moved to another inbox.
This is how you destroy the platform. When you block legitimate users, the users will think the platform is broken. Because, none of their comments are working. They can't see posts properly.
They don't know this is due to admins defederating servers. All they see, is broken content.
At this time, your best option is for admin approvals, combined with keeping tabs on users.
If you notice an instance is offering spammers. Lets- use my instance for example- I have my contact information right on the side-bar, If you notice there is spam, WORK WITH US, and we will help resolve this issue.
I review my reports. I review spam on my instance. None of us are going to be perfect.
There are very intelligent people who make lots of money creating "bots" and "spam". NOBODY is going to stop all of it.
The only way to resolve this, is to work together, to identify problems, and take action.
Nuking every server that doesn't have captcha enabled, is just going to piss off the users, and ruin this movement.
One possible thing that might help-
Is just to be able to have an easy listing of registered users in a server. I noticed- that actually... doesn't appear to be easily accessible, without hitting rest apis or querying the database.
This is all 100% correct. People have already written captcha-bypassing bots for lemmy, we know from experience.
The only way to stop bots, is the way that has worked for forums for years: registration applications. At lemmy.ml we historically have blocked any server that doesn't have them turned on, because of the likelihood of bot infiltration from them.
Registration applications have 100% stopped bots here.
You're right that captchas can be bypassed, but I disagree that they're useless.
Do you lock your house? Are you aware that most locks can be picked and windows can be smashed?
captchas can be defeated, but that doesn't mean they're useless - they increase the level of friction required to automate malicious activity. Maybe not a lot, but along with other measures, it may make it tricky enough to circumvent that it discourages a good percentage of bot spammers. It's the "Swiss cheese" model of security.
Registration applications stop bots, but it also stops legitimate users. I almost didn't get onto the fediverse because of registration applications. I filled out applications at lemmy.ml and beehaw.org, and then forgot about it. Two days later, I got reminded of the fediverse, and luckily I found this instance that didn't require some sort of application to join.
Don't read the first sentence, and then glaze over the rest.
Heh, stupid AI can't even be more smarter than me
Btw, what's the deal with your instance? I noticed you're from one of the original servers from 4 years ago. Do you know why it was founded or can you direct me to some information?
I'm from the reddit migration, although a bit more experienced than most (having been here over 2 weeks makes me a unicorn on my server).
I'd like to spread some more knowledge among my fellow newbies about the history of the platform and what kind of different servers are out there. Problem is, I don't have any knowledge! Help!
Ah, I see. So tchncs.de hosts other federated platforms, and someone probably decided to set up a Lemmy site when it was originally created 4 years ago. But it was likely pretty empty until the past couple weeks.
Ok good to know, I don't really know about XMPP/Jabber but I like what I see on wikipedia. Thanks!
chatgpt.
Despite all the hype about these things being able to solve all the worlds problems, they can't answer a series of contextual questions.
Boom. Roasted.
Haven't you heard of the "Swiss cheese" model of security?
The best way to ensure your server is protected is to unplug it from the Internet and put it in an EMF-shielded Faraday cage.
There's always a tradeoff between security, usability and cost.

I disagree. I think the solution is moderation. Basically, have a set of tools that identify likely bots, and let human moderators make the call.
If you require admins to manually approve accounts, admins will either automate approvals or stop approving. That's just how people tend to operate imo. And the more steps you put between people wanting to sign up and actually getting an account, the fewer people you'll get to actually go through with it.
So I'm against applications. What we need is better moderation tools. My ideal would be a web of trust. Basically, you get more privileges the more trusted people that trust you. I think that should start from the admins, then to the mods, and then to regular users.
But lemmy isn't that sophisticated. Maybe it will be some day, IDK, but it's the direction I'd like to see things go.
