Once you are suspended you are unable to post anywhere. Many many threads have returned to sanity by having a member suspended or banned. I assume you csn still read threads.
On the old platform, it would say banned under their name on every post they ever made even innocuous ones from way back. That doesn’t seem to happen now.
LK has always been cyclic in her posting habits. She is silent for a while, then has an interlude of bizarre posts for a few weeks then disappears. The posts seem to be driven by things outside of COTH, she will start opening up dormant threads with unclear replies to things said a year ago.
It’s also possible she has been suspended this time, but I don’t think the new platform makes that explicit, suspensions and bans seem to be more discrete now.
Also people can be blocked from specific forums, typically CE when political debates go toxic.
However couldn’t you go on as a guest and read things? Ah, but guests don’t get to read CE. And maybe not OT.
