Even if this person is a troll, setting up all of these communities and making multiple posts all across the place to audience of none is pretty fucking sad. I mean, look at this:
This person actually spent time typing all of this as if they're speaking to all of their close friends. And two days later there it still is with the one default upvote and no comments.
In fact, this is making me literally sad for this person now. They probably need professional help.
This is automated, not even that hard to code. More so if done in an separate instance. Also not hard to detect and autoban in theory on regular instances.
Lemmy needs a decentralized reputation system where all the big instances score people automatically so the fakes don't appear at all.
If darknet markets can do it, so can we. I'm a distributed systems security specialist. This is existing technology. We would require something like spamhouse etc. Everybody can run an email sever, but building reputation takes a bit. Blockchain can do some parts of that to make it auditable.
Not my area of expertise, so, I'd defer to those such as yourself. I absolutely think it's possible but, not simple to do in a resilient manner. Even with a publicly auditable ledger, there's a risk of becoming realistically unauditable due to massive quantity of data (as seen in some open source projects), which would need mitigations.
If you have any recommended readings or the like on such things, I'd appreciate them.
