She did get a warning

The only fine I've seen make the news was Janowicz getting $2500 for his outburst the first week. Is there a place on the web to get a full run down of all the fines from tournaments?

She did receive a warning. But, since she didn't do anything else, it didn't lead to greater punishment.

No. And I pretty sure janowicz fine was for the spitting.
