Can you find writing jobs on social networks? If so, how?

Answers including more than a simple "yes" would be strongly appreciated. Existing freelance platforms, such as Freelancer, Upwork, Guru, and other more or less known, are not the object of my interest right now. I would like to share what I have tried and discovered about the following ones. You say what you know and suggest.

LinkedIn

Had high hopes for this one, but it turned out to be a huge disappointment for me. Maybe, I didn't know how to use it properly. When I look for jobs, I had to use keyword "freelance copywriter/writer" + "remote." Send a couple of offers. Not a single response. There's some special feature on LN, I forgot how it's called for job opportunities. However, it is extremely locally oriented and therefore not of use for me.

Facebook

I heard there are some groups dedicated to writing. Yet, I have some doubts about them. What's a better thing to do? To create an individual account or join a group? If I'm going to move around FB as an individual writer, what's the best way to advertise? I'm skeptical about these groups. You need a group boss' permission to get it. Then, how clients order jobs? What's the distribution of potential jobs through these groups?

Twitter

Honestly, I don't have a clue how can you find a job as a writer on TW.

That's it. Now, if you know something and you're willing to share, please do so. Thx in advance.
