Well triple picking is a tricky thing :)
If it's really beneficial, than you should rather try to counter it, instead of getting it (because as mentioned before 1 counterpick can easily threaten all your bonuses).
As mentioned before, your friend should rather try to eliminate you from Europe, than block scan, and take another bonuses.
You from the other hand, should predict, that she triple picked and stay in EU hidden for 1-2 more turns.
Then after having CA + SA you just need to pop out in Ukraine with a stack. And even with income disadvantage you just using your positional advantage and stack to break your enemy bonuses one by one.
Here's exemplar game how to play against triple pick: http://warlight.net/MultiPlayer?GameID=6372515
You just need to sit in your ass and wait for right moment to pop out.
