Same here. Lost my interest and never able to gain it back.
Apparently my shadowbanned account was unblocked eventually and I can post normally from it again, but I know it was banned for at least 4 years, because I checked periodically (If you're not logged in, the user page looks blank. I thought it was some weird glitch but no, it's because I was shadowbanned).
I've been mostly posting in /r/coronavirus lately since I don't want to get into fights with friends on Facebook about my thoughts on it.
