Seems like a sociopathic trait. To try and get simulated attention for themselves. Nevertheless, it might work better for them the other way around. Using a smaller community on Lemmy as a ‘test’ environment and then plagiarizing a comment to get Reddit Karma. Or a post for that matter. I am pretty sure that there are people that might do this. There probably is a lot of mods on Lemmy that might tip off mods on Reddit for this very reason.

I will admit, if I need help for an answer to a question someone is asking, I DO Google and in those results there, which are often reddit, find someone who has already asked and answered said question, so I will just paraphrase them lol.

Not jokes but useful things and TOMT searches. Why reinvent the wheel?
