This is exactly what happened last time. It made it so most patrons who supported several people, had to narrow it down to one or two people at most (before they switched charging those extra fees to creators), which then destroyed the 1, 2, and even 3$ tiers.
Collectively we likely lost thousands of dollars the day this was implemented last time. Patrons were dropping like flies, people had to shut down their pages, it was trending on Twitter for days.
Do we really want to do this…AGAIN?
