"Inappropriate" names being blocked for no reason

When trying to change my Minecraft IGN to Klondike (a totally normal and PG name), it claimed it was unavailable. I checked the Minecraft API and NameMC, and the name is free to take (someone had it but changed it 38 days ago, meaning it should be available now.) After later testing, I found that every account with "dik" as a part of it was blocked, even ones that didn't use it inappropriately. I can see why they tried to do this, but it blocks thousands of completely appropriate names! Plus, accounts like "bigdik" and "dik" still exist, but names like Klondike are blocked. A better filter (or just manually sorting through "suspicious" names I guess) would work much better, and make family-friendly names like "Klondike" be able to exist.
