I noticed just lately while going over my articles comment section that there were marked as spam comments which I did not do even those red days of spammers. I think it was not a bug, it's the system doing it automatically when it detected a spam comment. And when we say "spam comment," comments like nice, like and other irrelevant comments. Maybe it was still on beta during its early days of marking spam when relevant comments were marked spam. what do you think?
