Enjoy. Or not.
@Sarah, told you it works.
NOTE: This also means "Spam" is now revised;
Point Value: 1 point
Definition: "A post containing no value, including off-topic posts or posts which derail threads."
With the advent of the "+1" system a "me too"/"i agree" post with no purpose or further elaboration of it's own in a discussion thread would also be considered spam as would "reaction" images.
Additional Comment: The word "derailing" here implies a train wreck sort of situation, not necessarily that the topic of the thread changed. Minor side tangents are not a violation of this rule unless the whole thread is impacted, or a request to return to the primary topic has been made and ignored.
Also note we can remove the ability to both like, and be liked, down to individual users if necessary, so abuse it, lose it. The eternal rule.
