I've just played a 3set match against I.Maturano for Australian Open and his attitude was really fairplay.
He showed me that he follows all the instructions to connect himself rightly and he wasn't cheesy at all in his game style according to the SIM rules.
If he had done something wrong before, I think he'll never do that again regardless his behaviour with me.
He's new here, he has maybe done an error before, but he looks very motivated for ITST anyway and seems to have the right spirit !
I can't say that about on3touch unfortunately
