if fiend any buyer profail can i sent mcg him?
No, because that would be spam.
It’s the equivalent of random salespeople calling your mobile to offer you a product you most likely don’t want.
It probably wouldn’t be possible anyway unless they’re also a seller since there’d be no contact option if they’re not also a seller. But it would be a against the TOS if you just contacted any buyer. You’re only allowed to contact them if they contact you first (eg. to reply to their messages).
It is not possible for any seller to send message buyer directly.
This is barely comprehensible.
Even if you were able to send a buyer a message (which is not possible unless the buyer contacts you first), an English speaking buyer would likely not be able to understand what your saying without quite a bit of difficulty.
