maybe. but somebody has to manually ban you if you do that. whereas banning everybody who charges back can easily be done in batch on the billing side

Retaliating against someone for asserting their legal rights also gets way riskier what they have already won in litigation.

Good luck surviving a real court case against any faang company. They could bleed any individuals bank account with delays and forcing you to pay hundreds of thousands in lawyers retainer fees for years.

The guy who invented the windshield wipers went bankrupt and had to wait something like 20 years for his case. He won but it probably wasn't worth it.

Good point. one off banning by hand may not be worth the effort, but some code to automate it probably is.
