Permanently Banned from a server and don't know why

[Destr2000]

got randomly kicked after playing with an SMR class in bo2.
server name: TDM BEST MAPS // HIGH XP // NO CHEATERS
can't find the server's website or discord to appeal that ban
my KD was 2.00 I think ( might be higher or lower but it was withing that range)

it says the reason was "Reason -SNTX" don't know what does that mean

does this ban affects me if I joined other servers?

[Xerxes]

No, that ban only affects you on their server not on others.

[Destr2000]

Xerxes thank you for your fast reply.

another thing.

by any chance, do you know this server's owners or how can I reach to them?

just want to ask him what does SNTX means?

[Xerxes]

no,no and no.
