I've set registration to Require application again, don't like this bots creating accounts.

Also I'm running into email limitations. Using the Sendgrid Free plan of 100 emails per day, but if a couple of member have email notification on, I'm reaching that 100 very quickly. How do others handle the high email traffic ?

Future spam accounts in the making. They are building large bot armies to either flood instances with their crap, or use them for vote manipulation, or a combination thereof.

It serves the same point it served on Reddit. There are huge bot farms dedicated to shaping the social media landscape. There is a new social media "boom" so the bots want to get in on the ground floor.

Concur. Instance admins need to be stamping these out with prejudice.

with what purpose ? posting stuff, or some other use ?

[–] [email protected] 1 points 1 year ago

It's a variety of purposes, but in this type of social media space it's usually to push specific agendas, often political. The accounts will often engage primarily by "reposting" comments to give a profile appearance that looks like a person. Then they engage in manipulations of conversation in specific ways. For instance, they might play "devil's advocate" in left-leaning political spaces to plant certain view points. One of the quirks of the human brain is that we tend to believe things we read over and over, regardless of the source, because volume breeds validity. It's a part of being a social species and being hardwired to be part of the herd.

If you hang out on social media and you read over and over, from multiple posts, that someone is a war hawk, that becomes part of your "sense" of them. Often these conversations are subtly shifted just by posting opinions with little to no substantiation. Your brain starts to think "wow, there are a lot of people saying that guy is a war hawk" and, since we're wired to conform to the group, you wrap that into your total opinion of the person. You'll also see just general "shaping" posts without a clear angle where the intent is to shape your perception of a public figure negatively or positively.

Think about your opinion of a public figure. Just your sense of who they are. Do you actually know facts that guide what you feel, or do you just have a sense of them based on all the things you "know" about them?

I read somewhere that you can add a captcha to registration, maybe that'll help filter some of the bots out?

[–] [email protected] 4 points 1 year ago (2 children)

Try enabling the captcha in your instance settings, it might help a bit as well!

[–] [email protected] 3 points 1 year ago (2 children)

While looking for a way to enable captchas I found out that they will remove that feature from lemmy: https://github.com/LemmyNet/lemmy/issues/2922

[–] [email protected] 3 points 1 year ago

That's unfortunate. A lot of bots have beaten them but it still stops a lot of low quality bots

[–] [email protected] 1 points 1 year ago (1 children)

Wouldn’t it help to force registrations solve an expensive proof of work on the client side?

[–] [email protected] 2 points 1 year ago

That would probably only slow them down. And since their main goal is to create a ton of working accounts, speed is probably not that important to them. On my own instance the bot-registrations stopped immediately after I enabled the required application.

[–] [email protected] 3 points 1 year ago

Captchas are mostly useless nowadays against any well designed bot. The only ones that sort of work are those ridiculously hard ones like several page math problems. And at that point a large portion of people can't solve it either.

They also tend to be full of trackers and are terrible for privacy. Plus they're used to train corporate AIs.

It can help temporarily, because a lot of bots don't bother with captcha solvers, but all the spammers need to do is include a pre-made solver library and the bots are back.

[–] [email protected] 2 points 1 year ago

Probably potential spam accounts.

[–] [email protected] 1 points 1 year ago (1 children)

My modlog got spammed today by some script banning a lot of people for spam automatically. It's getting wild. This was inevitable with the growth of Lemmy as a platform though.

[–] [email protected] 2 points 1 year ago (1 children)

Mine too I see now. You can only ban a user when they have posted something right ? There is no list for admins of all users registered ? Maybe I'll do it direct in the database..

[–] [email protected] 2 points 1 year ago (1 children)

Just did that for my instance. Luckily it's fairly easy. Since there were no human registrations after those bots I just looked up the lowest bot id in the local_user table which was 9 and then used delete from person where id in (select person_id from local_user where id >= 9);. Thanks to the references and triggers on the table, the rest of the database was also cleaned up by that, including the local_user table.

[–] [email protected] 1 points 1 year ago

For me it were the last 30 or something entries in local_user. They all didn’t have email_verified. I access the db through Postico. Also removed all other older accounts that didn’t verify their email address
