If an exchange starts consistently requiring KYC, or there are serious issues such as frozen funds, we can disable its rates/swaps and move it to the bad-reputation section rather than simply presenting it as a recommended option.
In this case, these services should appear first. Currently, there are 31 services listed in your list, and a quick check reveals that StealthEX, changenow, simpleswap, exolix, changelly, sideshift, changehero, and fixedfloat are all known to require KYC verification, and many of them are suspected of SCAM, not just requiring KYC.
You can improve the quality of your service by removing them and adding better alternatives.
