I scraped some web 2.0s and started registering them, couple days later I got this e-mail from DrupalGardens. It's been 30 days since you've last signed in to your Starter Drupal Gardens website at xxxxxx.drupalgardens.com. If you don't sign in to your website within 55 days, your website will be archived and then permanently deleted from Drupal Gardens, allowing us to provide a better experience for our active website owners. I decided to stop using them since it's pretty time-consuming making sure I login to these accounts, especially when you're creating multiple web 2.0s. Although if you use a bot like Magic Submitter or RankerX to post content I guess your good.
