Question:

how can i block countries to see me ? every time i blocked them they can see me ?

You can block countries via your ‘Settings & Privacy’ & saving when you have finished deciding which countries to block.  You can check to see if this setting has taken effect by visiting your own profile via another browser that you are NOT logged into.

You should see the following message:

‘Access Denied. This room is not available to your region or gender.‘

Once this is confirmed you may still have users from your own country, but this is down to users using a VPN to bypass the block that you have enabled.

Hope this helps.
