I'm not the user you were asking for the screenshots, but here they are. There's not really anything there worth screenshotting, it's the usual "nothing here" message, but this is what it looks like on old.reddit and a redlib instance.
Their fingerprinting methods are rather extreme. I was a little surprised I was still shadow banned when I tried making accounts on a totally new device a while back. But if you did roughly what this guide suggests, is there anything you did differently? If so, that might be where you want to start looking for how they were able to fingerprint you.
I'm sorry your comment seems to have been missed with no responses and no unbears after 2 hours, so I'll delurk to respond.
No, you don't need to read theory to post here or even to be a good comrade. In fact I would bet that at least 80% of regular posters here (outside the newsmega) do not read theory and also learned terms like "tailism" right here too. The misuse of terms like that happens here often enough that I think this must be the case. So do not feel bad about it at all!
That's not to say that you shouldn't read theory, because it will hone you into a better leftist and more capable of making informed analyses on anything from geopolitics to struggle sessions like this one. But be careful, it will also make you more adept at twisting your rationale to better suit your immediate position or what you want to be true (sometimes even fooling yourself), something else that I've seen demonstrated in this very thread.
I totally empathize with what you said about once being a voracious reader but not being able to anymore. It's exactly like that for me too. For me though it has a lot to do with attention span. Mine is just completely shot. Once I'm into a book a little ways, I keep having to reread the same paragraph 5 times to absorb it. My mind keeps wandering off even as my eyes follow the words on the page. I know what I need to do to improve it again, but it involves giving up internet treats like this site. (Maybe that's why some of the mods keep starting these obnoxious struggle sessions! They're trying to get us to log off long term and not rely on hexbear to be place where we can have fun posting among comrades, maybe? That's playing the long game, but it would explain a lot.)
Anyway, I give my solidarity and I wish you luck on staying alive for one, which I agree is difficult sometimes, but also that your extra hours and extra spoons line up better going forward. Reading theory is good and healthy and helps you grow as a leftist, but it's hard to get anything out of it when your life is so chaotic that you barely have time to read. But it's one of those chicken and egg sort of things... taking the time to read more despite the chaos might help in taming some of it. Only you would know if that's true in your case of course. But I know it is in mine.
I would comment more on the topic of this struggle session but seeing as I mostly agree with the people whose comments are getting removed, I guess I'll hold my tongue. ... Yep, it might be time for me to give up the leftist bear social media but take on more books again instead, I don't know. My favorite site/community turning so sour is not the motivation I would have wanted.
