### Dataset Summary

Focusing on young influencers from the well-known social platforms of Twitter, Instagram, and YouTube, we have collected a corpus composed of Spanish comments manually labeled on offensive pre-defined categories. From the total corpus, we selected 30,416 posts to be publicly published, they correspond to the ones used in the MeOffendES competition at IberLEF 2021. The posts are labeled with the following categories:
  - Offensive, the target is a person (OFP). Offensive text targeting a specific individual.
  - Offensive, the target is a group of people or collective (OFG). Offensive text targeting a group of people belonging to the same ethnic group, gender or sexual orientation, political ideology, religious belief, or other common characteristics.
  - Non-offensive, but with expletive language (NOE). A text that contains rude words, blasphemes, or swearwords but without the aim of offending, and usually with a positive connotation.
  - Non-offensive (NO). Text that is neither offensive nor contains expletive language
  
### Supported Tasks and Leaderboards

This dataset is intended for multi-class offensive classification and binary offensive classification.
