This is why I switched to $10+ tiers on Patreon, and later, Ko-fi. Less than that and you get a lot of impulse pledges. Most of them are fine, but it only takes one person who didn't read what was on the pledge page clearly to make trouble. At $10+, you get people who are mostly there for the journey and aren't troubled if you make big changes. The flexibility is worth not getting a few bucks from people who don't read before buying.
