Words and actions seem to differ. Recently they've been banning accounts or putting them under review (effectively same as a ban) just for 3rd party incest and other patches/mods, even when the dev has 0 control over that. And yes they large-scale do purges every 3 years or so it seems, happened in 2017 too. Regardless, fuck their narrow-minded terms. They should have told Visa to go fuck themselves along with any other sensitive snowflake that doesn't like it (no one is holding a gun to their heads forcing them to support creators they find offensive) and simply switched to a crypto-based payment system, it's why I only support devs on Subscribestar or Backed.by (anything allowed as long as it's otherwise US-legal, hurray First Amendment). As they say don't like it then don't play it (and least of all support it by subbing), somone else probably will one way or another.
