This has been bugging me for months and it comes down to one thing: is sexcht just a typo or a real hidden chat network?
My experience with sexcht just a typo or a real hidden chat network so far has been mixed enough that I stopped trusting first impressions.
Specifically on hidden chat network: what happened when you tried it, not what it says on the tin.
Genuine profiles are the scarce resource, and that applies to hidden chat network as much as anywhere.
