Nostalrius Begins - Quality wow vanilla realm (1.12)

Few minutes ago i was fishing on my 5 lvl character. After ~30 minutes i received a message from GM "hello".
I said "hello". GM said "What fish bot do u use?".
Me - "I dond use any bots"
GM - "Its your last words?"
Me - "Yes, its my last words - i do not use any bots".
GM - "Ok, your account has been banned for use a bot program".
WTF? I do not have time even make screenshot. Does all GM bans players without evidence and not given time to ask why did he decide that I use bot?
UPDATE: account name - mandor999
character: Doncarleone

Imo, something ''fishy'' was going on, on your end.

I dont used any fish or another bot. At this situation GM looks like a bot - standart phrases without any desire to know the truth. He may ask me something to check that I'm a man, but instead of this labeling me - bot and ban.
Even in such dictatorship country as Russia GMs dont ban players at servers without plausible evidence

Wow, the last thing this server needs is a GM like that. You atleast deserved some proof of how they knew you were botting.

Greetings.

Which GM did you talk to ?

I will take this further to the Admins for a check

Greetings!
I do not remember the nickname. I wanted to do a screenshot but was banned while using Google Translate. Mayme there is possibility to identify his nickname by my banned account - mandor999 or character name Doncarleone?

You have been banned for botting
