Possibly, and bots, though "many" is a relative term. There have only been between 15k to 20k active daily users (daily trusted pubkeys writing events) on Nostr the past two months, and just a little over 40k weekly. Lurking does not help #GrowNostr—we need more participation and posts on a variety of topics, not just tech and Bitcoin, if Nostr is to be successful in the long run.
