I don’t necessarily. But they have active accounts that do stuff and had the drop off activity consistent with “normal users.”

So it doesn’t matter to me if they were bots or not.

For example, 100 users clicked on the first link, 80 completed, and had normal account activity (clicking on stuff, uploading and downloading things, etc).

100 users clicked on the second link and then had normal account activity.

Maybe they were all bots, but they seemed human based on the “normal activity.”
