If you say "ABC is going to increase 10x because it has a funny name" that obviously won't fly, but if you give a detailed account of why it is possible (this is called DD - due diligence), this has much more potential to excite people. I wouldn't classify open source intelligence as a pump and dump.
It was the biggest crock of $$$$ I've ever heard, no element of truth to it. But it meme'd really well.
I’m no Wall Street guru but that doesn’t sound like a pump and dump scheme at all.
Some of the other stuff they do is kind of funny in a “some people just want to watch the world burn” kind of way.
It's not easy to make up artificial reasons as you will be forced to provide evidence for your claims. You need a solid base to build your argument and you better believe that you'll be fact checked in very aggressive ways.
But you don't need an account to view WSB, you are able to go browse it right now and see that it's mostly just stock market/economic news.
All pump-and-dumps have an X.
Having a narrative of how the thing you are pumping will go up is not a difference from other pump-and-dump schemes.
Posting technical analysis and/or positive news that encourages people to take a position is not a pump and dump. No more than any financial article that has ever been written.
