Italian call-outs have exposed a number of the most famous footballers, rappers and influencers in fashion and concerts.
Inter Milan's Mauro Icardi, Leonardo AC Milan and Kyara Virajni, the fashion blogger, were among the 25 listed blacklisters.
The list was published on Thursday on Milan's Facebook page, where the group calls itself a "political cooperative" for Milan's delivery workers, and was published by the major Italian media on Friday.
"This is our black list, a list of all the stars and dignitaries who regularly ask for food through electronic applications, and do not give a tip to those who deliver, even when it rains," the group wrote.
The group pledged to update the list regularly, while demanding trade union rights, fair remuneration and adequate social security for its members.
