this is an old topic I know, but how is the situation now??
I don't think it matters. The past can't be forgotten if they suddenly change their ways of doing business. Whoever is ready to scam once can do it again if the incentive is strong enough.
ChangeNow doesn't require KYC, except when they do because of reasons X, Y, and Z. You can decide to refuse to undergo KYC and get a refund of your deposit, except if X, Y, and Z. We are a non-custodial service, but we can freeze your funds until you comply with our demands. They will have to do much better.
If a person insists on using an instant swaps platform, I think it's better to consult BestChange. Enter the crypto pair and see what the best available offer is. Don't forget to do some research on the exchange you will be depositing your coins to of course.
