I do not see how getting rid of off-topic comments/replies will lead to a ban of the forum in Russia,its a laughable one really,are Russian citizens gonna be banned or our domain name banned in Russia..
It's basically impossible,if the moderator feels those subjects are off-topic he/she has the right to get rid of them,whether he/she be Ukrainian or what have you
The forum has rules and it's the duty of the mods to abide by forum rules and not those of respective countries
