That doesn't matter.
"Doping" is ingesting a banned substance. It is banned. If apple pie is a banned substance, and I am proven to have eaten apple pie, I am a doper. After the fact "oh it doesn't really help" does not relieve one from the duty to not ingest it.
Jumping off and not directed at your post, (although it may address some of the issues)
1. TMZ doesn't really help performance : irrelevant to whether the athlete ingested it.
2. No reason/motivation: irrelevant to whether the athlete ingested it.
3. They can't be that stupid: really? Someone came up with the gem that is Grandpa's Glass
4. Everyone else does it/all these other athletes got off: irrelevant to whether this athlete ingested it.
And yes, I will repeat myself every ten screens or so, just for good measure.
If Kamila is found to have a defense to the positive test after a hearing, then she is not a doper. If she does not, then she is. ETA: At this point, she was allowed to participate procedurally, but nothing has been proven to contraindicate the positive test. So as of now, she did "dope".
