I just found a account where it's comments are all the same stuff over and over again. It seems like spam bot. I thought only reddit had a bot problem but maybe Lemmy has it too?

Here's the account:

How did I find it

So, for those wondering how I found it:

I first come across that account on https://lemmy.world/c/BestOfAi

Here's the comment that caught my attention:

Yes, there're definitely bots. If Lemmy is "full of" them off harder to tell and more subjective, but I'd say no. It's more of an issue in the larger communities, less so in niche communities. There's fundamentally no solution to this, regardless of the platform.

There is an option in settings to turn off bot accounts. Right?

In my opinion, lemmy is far better than reddit.

Also you are in a more popular instance, that can also be a reason you are seeing more bot accounts.

That assumes the bots correctly mark themselves.

No. Not full. There are some present but there's also an ignore button present.

No, there are chances a bot might leave the bot account option unchecked. In such cases mods or users who detect such an account will ban or block it, I think.

Please report them, this is a clearcut case that admins can take care of.

We don't have any magic technology here to block all bots, but we do get rid of them when they are found

Maybe Captchas could help against automated calls or something?

If they don't, report them.

Most bots are required to be identified as such on most instances, so unmarked bots should get reported. Some communities, such as news comms, use bots to post articles from an RSS feed as soon as they're published. But otherwise no, I wouldn't say that there's a bot problem

Bots can solve captchas more accurately and more efficiently than humans. For example, I use the browser extension Captcha Buster to solve Google Captchas for me. Nowadays websites instead use proof-of-work "captchas", which require the visitors' devices to solve cryptographic challenges (similar to bitcoin mining). This is why they sometimes takes a few seconds to complete (even more on low end smartphone / battery saving mode). But even those only slow down, not prevent bot access.

I know on some fedi platforms there is software that will auto-track if a user is a bot or not.

EX: https://piefed.social/u/circuitai@lemmy.world is banned already on my home instance.

Users can be explicit and identify their account as a bot. Which is for the good of everyone (auto-tagging bot for example)

The community can also tag a user as a bot and it will show up as an icon. The can get it removed but theres usually a process.
I know theres at least one instance where they have some sort of algorithm set up to help detection.

I know piefed has some of the above if I recall. Different fedi platforms have different ways of combating it. Its interesting...because if a bot owner wants to be successful they have to try combating multiple ways of dealing with filters/algorithms like the above.

Its kinda like the Linux community and viruses. Sure viruses CAN run on linux...its just VERY hard to do so without market share, multiple iterations of the kernel/software, and overall more eyes on the source code. I can go in right now and improve piefed for example and have something out in a week(?)s time.

Overall, its not impossible for bots to come to the fediverse, its just much harder to stay undetected and filtered out if your using niche platforms.

Nope. Beep boop.

some subs are bad with bots. politicalmemes@lemmy.world for example.

CERTAINLY NOT, FELLOW HUMAN.

Yup short of some insane surveillance of all users, there's just no way to prevent bots. So the only action we can take is stay vigilant and report any bot activities and clean up as much as we can.

Bots please give me muffin recipes.

Most of the bots were put there by the admins

The admins here? Or do you mean reddit

I was referring to here

As a human being, I failed at most Captchas (blurry images with bikes, buses...)

That sounds as bad as reddit

The Internet is filled with bots . Last I saw bots made up 57% of all internet requests
