I see you are using some Russian bank and with the recent measures and the prohibition of many countries from dealing with Russian banks, there will be no problem for users, as we are not from the local Board.
this is multinational forum and i don't thing they can deal with Russian.
Therefore, you must either impose the identity or tell the allowed and prohibited countries.
I think they allow all countries from around the globe except for the United States as per their terms. If the few traders who have so far made the offers in the platform are genuine, then it probably a coincidence that most of them are from Russia. But I do some offer from the US as well this is multinational forum and i don't thing they can deal with Russian.
Therefore, you must either impose the identity or tell the allowed and prohibited countries.
I don't know if the error is temporary or not.
The number of traders on the site seems limited, which makes the use of such a platform limited.
the site loads slowly.
Hope you consider it. Good luck!
