But is this effectiive? I just scrolled back 10 days and opened the profiles of about 10 of these onboarded users, and I think a grand total of 2 have left a couple of comments, maybe 3 posts. The rest are one-post wonders, not a single interaction among them.

Is 2 half-kinda-maybe users out of 10 worth this extremely tedious onboarding mechanism of just contacting people one by one through DM? Seems to me it's just using up accounts that become ghosts within the day.

I'm attempting similar myself so it's not an attack that I'm pushing here. it feels like the stereotypical Indian Calling Centre hassling people around the world to buy double glazing windows.

Unless you can hire slave labour, I don't think this method is worth anyone's time. And it's worse than the Indian call centre because you have to expect them to keep coming back.

Traditional ads work, we know this because corporations have spent probably trillions by this point round the world researching it over the years. Can we learn from them?
