When I left Hubski some time ago I deleted my entire comment and post history by hand; this was rude and childish and I would like to apologise for that; it removed content that others had enjoyed and the below script is my attempt to fix that.

This uses ruby and the mechanize gem to login to Hubski and iterate over the deleted page for your user account, credentials are stored in a config file and gems are setup through bundle. This script was for my own purposes and does not have any error handling, but I did include a 2 second delay between items in order to rate-limit it and reduce possible impact to the site as it worked through 940+ items.

Apologies if anybody has been notified from being tagged in the posts -- as these were restorations it was not something I anticipated happening and only now considered.
