This remains unbelievable to me. I mean, one strike can happen, people make honest mistakes. But if that happened, you're already supposed to really be on edge.....then it happens again....
If you know that a third time will result in a ban, which it should, how are you not spending every day making absolutely sure, ten times a day, that all your whereabouts information and everything else is entirely correct? Ask your coach, ask your federation, ask your NADO, ask everyone to make sure you do it correctly...
Like Rastorgujevs in biathlon: he got a strike because he wrote down his address as "Stelvio, Bormio", which was obviously not enough to locate him (as WADA/IBU/whoever told him). He then got another strike unrelated to that, and later a third strike......because he wrote "Stelvio, Bormio" as his address again. Come on.
There might have been something else going on in her case, like not having anyone at all available to ask something to (teammates, coaches, federations and so on, maybe the relationships between them are bad, who knows), but ban or not, at least I hope she will learn to deal with the system...
