I just downloaded Primal and created a new npub, selected that I was interested in Bitcoin, Finance, and Nostr, and this is my immediate follow list.
FOLLOW LISTS FOR NEW NPUBS SHOULD ONLY CONTAIN THAT SAME NPUB.
This has led to npub follow lists full of spammy npubs. Anytime someone generates an npub, the npubs currently trending (or whatever metric they're using) get a new npub.
Effect is the same as follow bots.
Example:
nostr:nevent1qqswsryg0j2eh89e5uy5ruwvpydwaewhd30tspgsxaww39j6yzrlm6qn49spd
Discussion
If I select all of the categories, this is who my new npub is following.
Apparently, this isn't the only client doing the autofollowing because myself and hardly anyone I regularly interact with is listed (The list is incredibly myopic; no wonder people think we only talk about Bitcoin!), but we're being autofollowed by someone.
