[free app] Making bot Twitter accounts look legit

Ok, so let's say you have a Twitter account you use to post promotions, follow or retweet. You need to make it look active or water down the stream of promotions with actual content. I've made an app that takes your account and posts random tweets within 8 hour period each day, with random delays, to make it look more human. A few examples:
https://twitter.com/PaulsVanags
https://twitter.com/ValeryJKlein

It's a web based app I've made as an addition to http://socialacorn.com You can join it here: http://sacrifices.socialacorn.com/ Just enter with the account you want to "humanize" and fill in the "benefactor" field with "jackjsnow" (that's my main account). To stop the tweets - clear the "benefactor" filed. Any issues - let me know.

Hope someone will find it useful
