I disagree because Electrum 2FA makes a 2-of-3 multisig.
In generally, users would be far better setting up their own 2-of-3 multi-sig rather than relying on a third party, sacrificing all their privacy, and paying the excessive fees charged by TrustedCoin.
I don't think there's a way to determine the safest server, with the exception of the one hosted on electrum.org. You're basically trusting the node operator to not leak your privacy.
The only safe Electrum server is your own one.
So what its the solution?
Don't reuse addresses when you can. If you must, such as in recurring payments from a third party, use it for that one purpose and one purpose only - never reuse the same address for different purposes. And then as mentioned above, mix the coins you have received to prevent other tracking where they are going and what you are doing with them.
