I can understand how a particular team in one season can get penalised continually. They obviously are pushing the boundaries.
But when a club is penalised year after year, despite changes in personnel and coaches, then it is referee bias.
Over many decades Manly and Easts have been on the wrong end of penalty counts. I'm sure this is because both clubs are regarded as elitist and over-successful.
I'm also sure if you surveyed where referees played their junior RL that the Easts and Manly junior leagues would have produced the fewest.
I'm not sure that many RL supporters know this but referees are human, and even if they think they are being unbiased they subconsciously will favour the team that they like most, and which is behind on the scoreboard in order to create a closer and more interesting spectacle. The games against Newcastle was a perfect example of the latter. The refs, and vidiots, got the Knights back into that match, and that encouraged the crowd which helped lift the Kinghts' players spirits.
Really, this was a great win when all the odds were stacked against us.
