SpiderOak: Only as secure as the people handling your data

So, after dumping my Dropbox account in favor of SpiderOak, I've been pretty happy with them other than waiting on a few more features with their mobile app. Well, last night their desktop client started telling me that I was over my limit, when I knew that I wasn't. I double checked my account and restarted the client. After a few minutes, everything was fine. Then, today I received this email:

--------------------

Hello,

Early this morning, you may have received a notice from SpiderOak that your account is out of space even if you have plenty of space available. Please accept our apologies for the inconvenience! This was a server-side error which we have already corrected, so your account should be back to normal now. If you are still seeing the "Buy More Space" pop-up, please exit and restart the SpiderOak application. Any uploads which were in process will be re-added to the queue automatically.

Thank you for your patience while we resolved this issue!

Best, The SpiderOak Support Team

Followed by this email:

--------------------

Hello -

A few minutes ago I sent a message entitled "Out of Space Message" to approximately 500 affected users in an attempt to test automating this message. By accident, I included the email addresses of these users in the "to" line in plaintext. I am EXTREMELY sorry for this mistake and for the breach of privacy. I can only apologize for making such a terrible mistake and ask you to please delete the previous message as a courtesy to your fellow SpiderOak users.

Again, my sincere apologies for the error.

Best, Laura

Yes, the original email contained the contact info for numerous SpiderOak users. Even the most secure services can be compromised in some way, even if from within...
