I looked at his posts and did not see anything wrong. I have no reason to even suspect him of anything. IMO he is really putting in an effort to make quality posts (recently). When you stated that it does not sound human to you, I somehow understand where this assumption is coming from but without any proof it is merely a hunch (a hunch of a very reputed member, but still a hunch).
If you cannot substantiate your intuition, I am sure @Iamgoat will take it as a compliment. Clean chit from me .
