I am supervising a programming project whose goal is to detect offensive images on social networks. I would like to have a representative dataset of social network images. It would be best if the dataset were already classified. Otherwise, the classification of a (smallish) dataset could be a part of the project.
I looked around the internet and searched various dataset collections that are freely available, but I haven't been able to find anything appropriate.
What is the best way to get a large social network image dataset these days?
