It is enough to read reviews about this exchange: Tradesatoshi have the worst possible rating in terms of cryptocurrency asset security.
Yes, this is true. They are getting more and more "amazing" reviews.
So many, that Tradesatoshi is afraid that all this scam is coming out, so the moderators ask users not to publish any responses of support and even the numbers of tickets in public places, like discord.
It is extremely bad practice to disclose personal information on public places like discord.
It is very easy for a scammer to imitate admin and mod usernames .
Publishing your details in a public place allows scammers and phishers to target users.
For instance:
If you publish your ticket number and details - it can be used on the site to potentially "recover" an account.
A scammer can also use the details they read elsewhere to imitate exchange staff.
For this reason most exchanges will only deal with support tickets submitted through their site. It is an industry wide practice.
