Just about all of them... Pick any conspiracy claim on this site, and ask how they know. Ask where they are getting their information from and to cite their sources.

You will be called a jew and a lazy bastard for not doing "your own research".

If you're looking for a specific example, this is the one that prompted me to post this: https://scored.co/c/Conspiracies/p/17t1fUBWR3/x/c/4ZBIe9CT7xP?d=50.

It was a 144p potato quality video of some idiot filming his computer screen. And he was on some website looking at a weather map of the US, pointing at colors on the screen and calling them "electromagnetic waves".

I pointed out that this guy didn't even tell anyone what site he was on or what map he was looking at, much less how he determined what he thought he was seeing. And like usual, some idiot comes in and tells me I should "do research" and stop being lazy.

So that's a pretty good microcosm to serve as an example of what I encounter on this board all the time. Some idiot makes a ridiculous claim with nothing to back it up, which took them 5 seconds to compose, and when you're skeptical of it, they try and give you a 5 hour homework assignment to disprove it. And of course even if you took up the challenge, and debunked their claim with an encyclopedic level of thoroughness, all that will happen is they won't read it.
