I think this is caused by bot users. It has increased a lot recently. You can see this clearly by looking at the user acquisition metrics, it’s not normal to have such a big gap between the number of people who view the actor detail and input pages and the number of people who actually start the actor. I don’t want to block it with daily usage limits, data limits, or API restrictions (such as allowing it to run only from the console), but the alternative solutions tend to make it harder for legitimate users who just want to try the actor, and they are also difficult to explain.
