Straightlining policy?

Does Prolific have any policy or guidelines on rejecting participants who “straightline” while answering multiple choice questions? (meaning their answers look something like: 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, etc.)

Straightlining is an ongoing concern in my studies and I believe it would fall under the “low-effort” part of the rejection policy. I appreciate anything you have to share about this.

Thank you!


Generally speaking, do you have evidence that said straightlining is not genuine? Do you have reverse-coded questions or something that would indicate highly improbable combinations of responses? Otherwise, I don’t know what the grounds would be for rejection.
