What paying buyers said about each tool on this server: good and bad counts and the number of distinct wallets behind them, over a window you choose. Every verdict counted here was written by the wallet that paid for that specific call, one per settlement transaction, so the numbers cannot be inflated by anyone who did not buy. Counts only - no payer addresses and no review text, ever. Bad counts are published beside good ones, including ours.
