I noticed I was not able to read the feed for my Reddit account on either teddit.net or libredd.it - which concerned me. I then navigated to reddit.com/u/somenudist ('u' and 'user' should be interchangeable) and experienced the frowny face (as in the first attached screenshot) and the suggestion that my Reddit account has been banned. After at most a few seconds, the page would resolve to a broken feed (as in the first screenshot).
Is this what getting "shadowbanned" on Reddit looks like? Is it worth it to try and talk to Reddit staff about all this?
