What Tito did isn't against the rules. Its against the rules to create an unfair advantage with your alts, such as joining the opposing team with one of your accounts. However, Tito didn't do that here. What he did is perfectly fine.
Sorry for any offensive language in chat. Tito said he would report me for using offensive language and he was the only one swearing....
And you were the one behaving like an ass. Sure, the language that Tito used isn't appropriate, but it isn't unwarranted either. The main person who has shown rude behaviour in that chat is you.
About some things said in the chat:
Practising a 3v3 template in a 1v1 setting is completely useless. This is a decent way for Tito to practise, 1v1 wouldn't suffice.
Also lol @ telling someone who used to play poker professionally that they would suck at poker.
And the mods definitely aren't on your side, although Titos use of foul language didn't help him.
