I browsed reddit primarily with RIF for over 13 years, I made GDPR request for my data, and once I received it I edited all my comments to the copy pasta statement about reddit ruining itself, I then got summarily banned the day before RIF went 429. Made an account on lemmy.world. Feels like reddit during the Digg migration, I remember that exodus just as fondly.
"Summarily banned" means that something or someone has been prohibited or forbidden without a formal or lengthy process. It suggests that the ban was imposed quickly, decisively, and without extensive deliberation or investigation. In other words, it means that the ban was imposed promptly and without going through the usual procedures or giving much opportunity for discussion or defense.
