Hey there,
Today I'm selling a new Twitter script that has somewhat the same functionality that Twollow gives you. You plugin keywords and everytime that the script runs you'll follow people based on the keywords you provide. Most people you follow will follow you back, so its a very good way to boost your Twitter followers for marketing.
The script I'm selling is 100% customizable, you give it your Twitter username, password and keywords to follow. You can set it as a cronjob or do whatever with it, just not resell it.
It only costs $20 and comes with free upgrades for 3 months. If you are interested please email me at
caixetar@gmail.com or talk to me through one of the IMs listed on my profile.
Best,
Raphael
