I noticed on a recent question of mine that after I and another user discussed something in the comments a prompt (below the comments) came up saying something like "Please keep comments to a minimum, if you'd like to make a chat room, and continue click here". That isn't verbatim what I got, but it was something like it.
How does the system detect this? Is it looking for keywords or is there a comment count that triggers it? I ask, because I want to know, and to learn when or when not to continue commenting.
