One problem I see with your service is that governments and exchanges are randomly adding and removing addresses from blacklist.
And we all know that any coins seized and sold by governments are automatically getting whitelisted.
I think you should add source link that confirms when bitcoin address was blacklisted and who did it.
Also think about adding link for news and updates when new addresses are added.
I find this analysis unreliable because how can using a mixing service that protects user privacy be considered a high-risk activity? They even take mixing patterns as high-risk activity seriously?
It's all just a security theater 
I think they are doing something similar with decentralized Coinjoin.
