To solve my problem, I found the following solution by reading this page:

https://github.com/discourse/discourse/blob/master/app/assets/javascripts/discourse/app/lib/plugin-api.js#L1138-L1140

<script type="text/discourse-plugin" version="0.8">
    const specialTopicUserId = 1000;
    api.decorateTopicTitle((topicModel, node, topicTitleType) => {
        if (topicModel && topicModel.user_id === specialTopicUserId) {
            $("#topic").addClass("anon");
        }
    });
</script>
