Kickstarter has updated its guidelines to prohibit certain types of adult content, including violent, derogatory, and sexually explicit material. The change is reportedly due to pressure from payment processor Stripe, which may refuse to process payments for projects featuring such content. This move follows similar actions by other platforms, such as Steam and Itch.io, which have also faced pressure from payment processors like Visa and Mastercard. The change has sparked debate about censorship and the role of payment processors in regulating online content.
