Hi, Asher,
Yes, it looked a little "odd" to me.
Thanks for your continuing diligence.
Doug,
It puzzled me that I couldn't, at first, find the link back to the site (s)/he was promoting. Clever to swamp us with simple comments of approval. The number of posts he made might add weight to the eventual link's importance and rank for Google's sophisticated algorithms.
I wonder to what extent the process is automated and the sentences are bland enough and find content that allows it to seem natural.
Often, the track is in some gif which has built into it some clever link. So I had to invest 2 hours to deal with this.
Either this was a naive person who doesn't belong here or else a spammer. It took time to work it out. Certainly, we can't have the work of our genuine OPFrs buried in an avalanche of simplistic comments that add nothing of value.
Asher
