If you want to go on a LiveJournal a mass delete spree but keep your account active for the moment, and have access to a Windows box, lj-sec worked like magic. It just wouldn't let me delete more than 500-800 entries/hour.

I had to install a specific version of .NET on a Windows 10 machine, and after that, it went smoothly.
