I don't have much to add to the subject. I'm seeing an uptick in spam.
To clarify, by spam I mean the same stuff you'd consider spam if it came in your email inbox. I don't mean indie hackers mentioning or linking their work in posts or comments on the platform.
An example of the spam I mean is a user who joins Indie Hackers, doesn't fill their profile, and almost immediately drops into one or more consecutive posts just a bare link to a commercial product or service you wouldn't typically associate with indie hackers.
