My guess: (pure speculation)

Lemmy (edit: I mean the comment section) is probably at 25% government agents or people acting on behalf of governments including US, Russia, China, possibly other allies of the aforementioned.

Bots tho, probably few, maybe 10% or less. Most of the instances use manual applications, so hard to get bots through. You'd need to write a different "essay" for each application, also think of unique names that doesnt look bot generated.

If you look specifically in (edit: the comments section of) political threads, probably anywhere from 25% to 50% government agents.

Mainsteam social media like Reddit, probably at 25% to 50% bots pre-exodus, now it seem like 50% to 75% bots, the percentage of government agents are probably much lower, since unlike Lemmy where there are much less users, on reddit they wouldn't have the manpower to post enough comments to manipulate the discussion, but they could just use bots instead, many of those bots are probably operated by governments. And on political subreddits, these numbers will skyrocket.

Thing thing about the internet, is you have to treat it as entertainment, not real source of unbiased information, especially not a forum where any rando can sign up.

I'm gonna restate what I said in another thread:

::: spoiler

I’ve come up with a system to categorize reality in different ways:

Category 1: Thoughts inside my brain formed by logics

Category 2: Things I can directly observe via vision, hearing, or other direct sensory input

Category 3: IRL Other people’s words, stories, anecdotes, in face to face conversations

Category 4: Acredited News Media, Television, Newspaper, Radio (Including Amateur Radio Conversations), Telephone, Telegrams, etc…

Category 5: The Internet

The higher the category number, means the more distant that information is, and therefore more suspicious I am.

I mean like, if a user on Reddit (or any internet fourm or social media for that matter) told me X is a valid treatment for X disease without like real evidence, I’m gonna laugh in their face (well not their face, since its a forum, but you get the idea). :::
