The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed.

Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19

Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.

Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

My guess is that it'd make it look like it were actual ukrainians spreading the disinfo, as the IP wouldn't show russian addresses. Could also be that Ukraine is blocking internet traffic from Russia, so being there is a way to bypass the block.
I fully expect the assholes behind said farms to be safely within russian territory, so they're just sighing and shrugging as having to set up a new base.
Still, being physically there is weird. Aren't there reliable ways to fake it?
Depends what you mean by "faking". You can fake Ukrainian IP by using some VPN service, but then you're using VPN IP which is quite obvious. If you want many genuinely residential IPs, you could use some botnet and infected computers in Ukraine. This is more authentic and harder to filter out. But some services actually require phone number and at least capability to receive texts to verify the number, some use the number as user account. (Telegram and such) Then you need actual SIM cards (not to be confused with Sims 3, the game 😉) and you need to connect to local cell tower. (perhaps you could do roaming, but that would be quite obvious long term) Now to fake all that, you'd need at least some devices operated in Ukraine and at that stage it's probably easier to find some people willing to do this locally for money or because they are high on russian propaganda themselves.
Do you need to connect to actual celltowers tho? I know legit SIMs are a kind of a barrier, but then...
Using a portal through KZ to an UA endpoint via VPN\proxy, faking geoloc and other identifying stuff on your device.
For me, it sounds like enough, and a collaborant is only holding an exit node that is easier to defend in court than having all infrastructure at their place.
Well you do if you want to receive the confirmation text. And while you're at it, you might as well use the same cell tower for data so that you get "residential" IP.
You can definitely fake geolocation and perhaps you could fake IP through some proxy, but you can't use commercial VPN services as their IPs are well known VPN IP ranges at this stage. (these SIMs might have been used as such proxies for some spamming besides being used for this specific botnet) Effectively the more you want to blend in with the actual Ukrainian end user traffic, the more you need to be present in the country and the more complicated it is to fake it otherwise. Especially if you're trying to hide from state level investigation, that has access to triangulation from cell towers, providers logs, etc..
It's just I see one collab having a gateway on their PC for russian-based labs to operare rather than the whole scheme based oin Ukraine.
Cell-tower data would be hepfull to locate the guy, but do web\apps collect it?
You can do the gateway on a PC thing. You don't even need to have collaborator to do that, plenty of people run outdated systems riddled with malware.
But once you need actual working SIM (Telegram, Watsapp, etc..) you really need that SIM somewhere in Ukraine. And you need plenty of them. (see the pictures in the article, there's a ton) At minimum to activate the accounts and more realistically for occasional re-verification. (2fa) Sure you can then run actual bots in russia, but that need for physical presence is still there at least occasionally. The article mentions 100 individuals, when you consider that 150k SIMs were there, most of the operation indeed was in russia or somewhere else.
The triangulation is just a way to maybe correlate multiple SIMs in the same spot by Ukrainian officials once they had enough suspected malicious SIMs. (So that they know it's not just few random persons with malware on their phone, but it's indeed huge concentration of SIMs in one spot)
Thanks for your detailed answers.
