To share with friends who moved from #Twitter to #Threads:
"#Meta acknowledged…to The Washington Post that Threads is intentionally blocking the search terms ["covid" and "long covid"] and said that other terms are being blocked, but the company declined to provide a list of them. A search by The Post discovered that the words…“coronavirus,” “vaccines” and “vaccination” are also among blocked words."
