my understanding is that an infraction does not always relate only to the individual post upon which it was based.

that is, all posts made by you in that thread may be considered, for something like harassing someone - each individual post may not be that bad in itself, but the fact that someone made 15 posts in a short time may justify the infraction.

as far as it seems from your post 'man up john and come clean', it in no way relates to the original topic of the thread, therefore could be considered spam, and an infraction for 'spam' seems appropriate
