It always alerts me at the top of the comment section when there is a "suspicious comment" I usually just mark them as not spam and move on. You just have to pay attention to the comment count spot. I never paid much attention to why it happens since it always tells me that it is happening, and it doesn't happen very often.. and the same person can comment like three times in one post and 1 of the 3 get the suspicious comment on it, it seems random to me.
