Hey mate, sorry to hear about this. YT's been banning channels for a few months now, no matter the language and it's always the same reason, i.e. violating TOS. Russian channels on the other hand all get the same message, that they are banned for Scam and Misinformation (something like that) even though it isn't the case and may as well be copyright, but YT just gives the same reason to everyone for banning the channel and not giving any strikes beforehand. It is part of their strategy to cleanse YT from channels that are advertiser unfriendly. If your content was not made by you or you do something fishy there, then bad luck mate. Appealing won't help as this is YT's final decision (and trust me, I've tried everything to help a person reinstate their channel) and they will only change their mind if you had a big legit channel that was closed by mistake (and only if backed by an MCN).
