  text: This paper addresses new challenges of detecting campaigns in social media,
    which emerged with the rise of Large Language Models (LLMs). LLMs particularly
    challenge algorithms focused on the temporal analysis of topical clusters. Simple
    similarity measures can no longer capture and map campaigns that were previously
    broadly similar in content. Herein, we analyze whether the classification of messages
    over time can be profitably used to rediscover poorly detectable campaigns at
    the content level. Thus, we evaluate classical classifiers and a new method based
    on siamese neural networks. Our results show that campaigns can be detected despite
    the limited reliability of the classifiers as long as they are based on a large
    amount of simultaneously spread artificial content.
