Based on their profiles, one might at first think that these six Bluesky accounts belong to activist groups on a mission to defend democracy, or something of that sort. In reality, they're just reply spammers responding to random posts from liberal accounts with unsolicited AI-generated replies.

The case around oil tankers Eagle-S, which is most certainly responsible for damaging the Estlink-2 undersea cable, is getting even more interesting. It appears that ship was not only involved in sabotage but in espionage, as well.

Grundsätzlich schwer zu sagen. Zwei Möglichkeiten: 1) Die Folgen tausenden (>100,000) Accounts und gewinnen dadurch "back follower". (komisch, aber nicht verboten) 2) Bekannte Persönlichkeiten, die von X gekommen sind und daher ohne Beiträge viele follower haben.

2/ This is less than it seemed, based on how the replies to these news articles were dominated by the network (now often called vanillasky network). However, the network was likely still being developed. The oldest account first posted 4 days ago, while approx. half started posting 2 days ago.

Yesterdays thread on the discovery of an AI bot network gained quite some traction. Since then, ppl. found out more about the network. 1/ @badlogic.bsky.social and other's found that the bots are hosted through the same domain, which now has a total of only 19 bots. 10 of which are blocked by Bsky.

The accounts were less just a few hours/days old. Roughly half have been deleted by now - so it seems BlueSky is doing a good job! They might still rely on us for reporting suspicious activities though.

And just to quantify the OPs claim that Bluesky is being flooded with German speaking bots. This tiny network hat 19 bots, which posted a total of 182 posts (at least the 10 bots that are still active). That's not quite a flood. Pretty sure as the elections come closer, we'll se more activity tho.

Die bots aus dem thread haben mit niemandem interagiert. Rein technisch dürfte das aber Möglich sein. Fliegt aber ggf. schneller auf, wenn die Antworten weniger Sinn machen. Das Hauptproblem ist, das die mit der Zeit besser werden könnten.

In other bot news, these bots are on their on "Personal Data Server", which is still running. There are a total of 19 accounts on that server. Only 9 of them have been suspended. Curious why @support.bsky.team hasn't defederated with that PDS entirely?

/5 How is this different from bots in the past? With gen. AI posts bot networks can act in any language. They also have a simple understanding of the posts they reply to, making them much more authentic! Bear in mind, that this is probably a crude example. More advanced networks may not be spotted.

Lion Cassens @lion-c.bsky.social · 07/12/2024
/4 Why build a German speaking bot network if they don't post strong opinions (yet)? While this is largely speculation, one should consider that Germany holds elections soon! By growing reach now, such an AI network will then be able to significantly steer what people see on Bsky! See #romania.

Lion Cassens @lion-c.bsky.social · 07/12/2024
/3 What are these German speaking bots up to? Each account posts only under German news articles (e.g. @spiegel.de). But here is the catch: its not the usual strong conspiracies or fake news. All posts rather neutral. My guess is that the goal is to first generate followers...

1/ What are the indicators these posts are even fake? All responses have a similar style (textbook-like, neutrally written) and do not really respond to the article. Instead they just use generic phrases, while also somewhat being adjusted to the post. All accounts only reply / have similar bio's.
