I think it needs to be fixed.
Well nothing much can be done I think as they are offering their serviece. We either wait for exchanges to implement LN or it stays this way, nothing much can be done since some are free even. To be honest I don't mind them and don't even bother, what is the problem if we use free serviece there and guy simply accelerate my transaction? Even if those people use serviece like viabtc tools, my transaction got confirmed and I haven't spent my time spamming transaction myself until it got accepted.
I understand paid ones are a bit tricky but hey this is not illegal thing to do.
Why are they scammers? I don't see any reason for that if I chose those free accelators out there that people offer.
