StumbleUpon destroyed my blog

I hope this works and is shown for I am angry with the 'StumbleUpon' people. I followed their directions in adding adding their symbol on all my posts so that people can click on it to get my page more circulated on the internet but no, all it did was delete ALL of my posts.

I have sent them a complaint that was short and sweet. I was considering closing this blog. I think it's more than likely that I'll close it now since StumbleUpon completely fucked it up.
