This paper discusses the negative comments on the tweets attacking the "tiga ronde'' poster during the student protest on April 11, 2022 that went viral on Twitter. This is a qualitative study, using the appraisal theory as an analytical method. The data collection is carried out by taking random tweets within the discourse of poster “tiga ronde”, which are then sorted into ten tweets as the appraised items. The appraised items were translated from Indonesian to English. We then look for the word with the closest pragmatic meaning to the translated word in the semantic resources of the appraisal framework. Lastly, we categorize whether the appraised word is classified into affect, judgment, or appreciation. The aim of the study is to understand the attitude of those negative comments. It is presumed that the intended meaning of the comments, whether it is an affect, judgment on the poster's writer, or appreciation on the poster can give a better understanding of why they are used to attack the poster. The study reveals that a lot of pseudonym accounts give judgment towards the writer’s behavior rather than appreciating the poster or expressing their feelings about the phenomenon.
