Another PL seller here with a few brands and a couple hundred products:

"No brand name" flag is tricky because the Amazon catalog team actively does A/B tests to hide brand names as part of their goal of commodifying all the sellers to increase price competition, when they see you're selling a commodity item.

Same goes to wellknown brands that get caught in the crossfire because they're using their brand name from another language but don't make sense in English.

Agreed that it's an interesting idea, but execution has a LOT of false positives.
