existe baneo este caso? Does this case exist?

Yes, all games need to be activated on the account you won them with. You are also allowed only one account on SG: Having multiple accounts for this platform will lead to a permament ban of all of them once discovered.
However, you will only receive a temporary suspension for a non activation, even if it was an honest mistake.

Edit: your profile is even showing two unactivated wins. A mistake seems unlikely in two cases. If you have enough non activations, you will also be permantly banned from this site.

One way to solve it is to buy the game for the main account.

Note also not to use 2 accounts or more on this site, and if it's a family member's, then you have to write a support ticket.

What eeev said above me, and I'd like to add that you can fix it by obtaining another key for the game that you activate on your Steam account that is linked to Steamgifts.
Or as a dirty solution you could ask the giver to delete the giveaway. You could negotiate a compensation for it.

If left untouched, the future is dark.
The explanation of the people who said earlier is all.
Anyway, it is to consult from a support ticket.

You can close this discussion from the top right if you do not want to confirm anything else.

You realize that you've got one more unactivated win (Divinity: Original Sin), right?

was delivered by gift, I must change my market to Russian to activate it, with that I have no problem

Tienes dos juegos sin activar en tu cuenta, compralos y redimelos en esta cuenta, no esta permitido tener múltiples cuentas en SG, solo usa esta.
