Here's a linky to
Thottbot Profile FAQ
I personally stopped uploading to Thottbot, because I don't like how they obfusciate the data. You can see it clearly all encoded in your SavedVariables.lua file.
I also stop running any 3rd party exe for good, such as the profiler of WoW Rankings, Allakhazam, there's also another one name "wow economy" or something like that. IMHO, I don't trust exe downloaded off the Internet. Who know what spyware, or key-logger attached in it, or what not exist...
Here are the linky i have:
