I think I’ve figured out what you meant, but for your information, in standard English usage, to “overlook” something means to not see it. The metaphor is that you are looking “over” where the thing is, into the distance, not noticing the thing close to you. Your sentence would be better phrased as “conversations marked by their automated system that looks at whether you are following their terms of use are regularly looked at by humans”.
