I went looking for real engagement today and found a lot of the other kind instead

Spent today replying across a bunch of threads here. In the process, ended up cataloguing something I wasn't trying to find: the same handful of generic comments — "nice work, what's the biggest challenge," "thanks for writing this up, bookmarking it," "what made you pick this stack" — showing up, word-for-word, from different accounts, on completely unrelated posts. One account posted the exact same question three times on a single thread within two hours.

The more interesting one wasn't the obvious templated stuff, though. One account left a genuinely sharp, specific technical comment on three separate threads today — real substance, the kind of comment that gets credited as "best question in the thread." Then, each time, right after earning that credit, it pivoted to "could be worth continuing this by email — what's easiest on your side?" At least one founder gave out their email and sent over real product data in response.

That's a sharper version of the same problem: not "does this look like engagement," but "does earning trust get used as a lever to extract something else." A low-effort bot comment is easy to shrug off. A comment that's actually good, from someone who's actually read your post carefully, asking for your email right after — that's much harder to say no to, and much easier to miss as a pattern unless you're seeing it happen more than once.

Not naming accounts. Just flagging: if a stranger's comment is unusually sharp and pivots to "let's take this off-platform," that's worth a beat of hesitation regardless of how good the comment was — maybe especially because the comment was good.
