Isn't not knowing how often it happens more concerning that knowing?
In order to fear something, you need to have some examples. I can also refer to the fact that it is too risky to use trains, because a meteorite can fall on the train. Interestingly, how many such cases have been recorded in general in order to seriously fear such a development of events as a meeting of a train and a meteorite?
Maybe it just happened. Their terms of use make it clear enough that you must not share the ownership with another person, unless you have Binance's consent.
And I totally understand why they don't. Because users can exist without exchanges, but there is no exchange without users. Clients are their business and it is not in the interests of the exchanges themselves to make the number of these clients decrease for one reason or another. That is why the exchanges write all these prohibitions formally in order to comply with the regulations and licenses issued to them. This is the only reason why they introduce KYC for their clients or restrict certain jurisdictions.
In any case, I am not advocating for anyone to use this behavior when interacting with centralized exchanges, which is used by me or anyone else. Everyone should make their own decision, I'm just sharing my rich experience of interacting with these services and talking about them from the point of view of a real client of these exchanges.
